[0020] A further technical solution is to use a second diversity wireless ad hoc network to set the frequency of each receiving channel, including:

[0021] According to the frequency information of the transmitted signal, multiple sub-channels on different receiving channels are set to different initial frequencies, wherein the initial frequency of each receiving channel is the same as the available frequency of the corresponding service to be processed.

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0049] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] Wireless ad hoc network is a form of wireless network that can be established without infrastructure, with the characteristics of self-organization, multi-hop communication, dynamic topology, etc. This form of network is very suitable for rapid deployment in environments without fixed infrastructure, especially in emergency communication scenarios, such as earthquakes, fires, typhoons, floods and other disaster rescue processes. It can be quickly networked and portable installed to provide timely and effective communication guarantee for rescue.

[0051] However, most traditional wireless ad hoc communication signals are received and processed using a single channel. Figure 1 .

[0052] For example, a conventional wireless ad hoc network communication device 10 includes a receiving unit 100 and a software processing unit 200. The receiving unit 100 may include two antennas and four receiving channels. The two antennas are ANT1 and ANT2, and the four receiving channels are RX1, RX2, RX3 and RX4, wherein RX1 and RX2 are both connected to ANT1, and RX3 and RX4 are both connected to ANT2.

[0053] The software processing unit 200 includes an editing unit such as a Field Programmable Gate Array (FPGA) and two digital signal processors (DSP), which are DSP1 and DSP2 respectively.

[0054] The services to be processed are service 1 and service 2. Service 1 has frequencies of 410 MHz and 411 MHz, and service 2 has frequencies of 412 MHz and 413 MHz. Antenna 1 is connected to service 1, and antenna 2 is connected to service 2. DSP1 processes the output signal of service 1, and DSP2 processes the output signal of service 2.

[0055] According to the frequencies of service 1 and service 2, the frequencies of RX1, RX2, RX3 and RX4 are set to 410 MHz, 411 MHz, 412 MHz and 413 MHz respectively.

[0056] When service 1 initiates a service at a frequency of 410 MHz, RX1 of ANT1 receives the service signal, and after two down-conversion processes, demodulates the analog in-phase quadrature signal (I n-Phase Quadrature, IQ signal), and then passes through the ADC chip (such as Figure 1 The CMX981 in the system converts the IQ signal into a digital signal, which is then input into the FPGA and distributed to the DSP1 for corresponding frequency modulation (FM) and quaternary frequency shift keying (4FSK) demodulation.

[0057] When service 1 initiates a service at a frequency of 411 MHz, RX2 of ANT1 receives the signal, obtains the digital IQ signal in the same way, and distributes it to DSP1 for corresponding FM and 4FSK demodulation.

[0058] Similarly, when service 2 initiates a service at a frequency of 412 MHz, RX3 of ANT2 receives the service signal, performs two down-conversion processes, demodulates the analog IQ signal, and then passes through the ADC chip (such as Figure 1 The CMX981 in the system converts the IQ signals into digital signals, which are input into the FPGA and then sent to the DSP2 for corresponding FM and 4FSK demodulation.

[0059] When service 2 initiates service at a frequency of 413 MHz, RX4 of ANT2 receives the signal, obtains the digital IQ signal in the same way, and distributes it to DSP2 for corresponding FM and 4FSK demodulation.

[0060] It can be seen that the signal sent by the above-mentioned service 1 is only processed by RX1 or RX2 connected to ANT1, and the signal sent by service 2 is only processed by RX3 or RX4 connected to ANT2. That is, in this method, only a single channel is used to process the communication signal of one service. Therefore, this method can easily cause the communication signal to be intermittent, or even unable to establish a stable communication connection, thereby affecting the communication quality.

[0061] Based on this, in order to solve the technical problem that the existing wireless ad hoc communication signal adopts a single channel for receiving and processing, resulting in poor communication quality, the present application provides a communication signal processing method that can improve call quality and communication distance. Please refer to the following embodiments for details.

[0062] The wireless ad hoc network communication device 10 provided in the present application includes a receiving unit 100 and a software processing unit 200. The receiving unit 100 may include multiple antennas and multiple receiving channels, wherein each receiving channel corresponds to an antenna, and each receiving channel includes at least one sub-channel.

[0063] The following is a detailed introduction to the communication signal processing method provided by this application. Figure 2 , Figure 2 1 is a flow chart of a first embodiment of a method for processing a communication signal provided by the present application. The method comprises:

[0064] Step 110: Acquire the transmission signal of the service to be processed.

[0065] The number of pending services may be one or more.

[0066] Step 120: Utilize multiple sub-channels on different receiving channels to respectively receive and process the same transmission signal to obtain a multi-channel processed signal.

[0067] For example, see Figure 3 In some embodiments, the service to be processed is service 1, the antenna includes antenna 1 and antenna 2, the multiple different receiving channels may include a first receiving channel 110 and a second receiving channel 120, the first receiving channel 110 includes a subchannel RX1, and the second receiving channel 120 includes a subchannel RX2.

[0068] When service 1 initiates a service with a transmission signal with a frequency of 410 MHz, the sub-channel RX1 of the first receiving channel 110 is used to receive and process the transmission signal to obtain a first processed signal; the sub-channel RX2 of the second receiving channel 120 is used to receive and process the transmission signal to obtain a second processed signal, thereby realizing the use of multiple sub-channels RX1 and RX2 on different receiving channels to respectively receive and process the same transmission signal, that is, the transmission signal with a frequency of 410 MHz, to obtain multi-channel processed signals.

[0069] Similarly, when service 1 initiates a service with a transmission signal with a frequency of 411 MHz, the frequencies of sub-channel RX1 of the first receiving channel 110 and sub-channel RX2 of the second receiving channel 120 are adjusted to 411 MHz, so that the transmission signal is received and processed by sub-channel RX1 of the first receiving channel 110 to obtain a first processed signal; the transmission signal is received and processed by sub-channel RX2 of the second receiving channel 120 to obtain a second processed signal, thereby realizing the use of multiple sub-channels RX1 and RX2 on different receiving channels to respectively receive and process the same transmission signal, i.e., the transmission signal with a frequency of 411 MHz, to obtain multi-channel processed signals.

[0070] For example, in some embodiments, the service to be processed is service 1, the antennas are antenna 1, antenna 2, and antenna 3, the multiple receiving channels may include a first receiving channel 110, a second receiving channel 120, and a third receiving channel, the first receiving channel 110 includes a sub-channel RX1, the second receiving channel 120 includes a sub-channel RX2, and the third receiving channel includes a sub-channel RX3.

[0071] When service 1 initiates a service with a transmission signal with a frequency of 410 MHz, the sub-channel RX1 of the first receiving channel 110 is used to receive and process the transmission signal to obtain a first processed signal; the sub-channel RX2 of the second receiving channel 120 is used to receive and process the transmission signal to obtain a second processed signal, and the sub-channel RX3 of the third receiving channel is used to receive and process the transmission signal to obtain a third processed signal, thereby realizing the use of multiple sub-channels RX1, RX2 and RX3 on different receiving channels to respectively receive and process the same transmission signal, that is, the transmission signal with a frequency of 410 MHz, to obtain multi-channel processed signals.

[0072] Similarly, when service 1 initiates a service with a transmission signal with a frequency of 411 MHz, the frequencies of subchannel RX1 of the first receiving channel 110, subchannel RX2 of the second receiving channel 120, and subchannel RX3 of the third receiving channel are adjusted to 411 MHz, so that subchannel RX1 of the first receiving channel 110 is used to receive and process the transmission signal to obtain a first processed signal; subchannel RX2 of the second receiving channel 120 is used to receive and process the transmission signal to obtain a second processed signal, and subchannel RX3 of the third receiving channel is used to receive and process the transmission signal to obtain a third processed signal, thereby achieving the use of multiple subchannels RX1, RX2 and RX3 on different receiving channels to respectively receive and process the same transmission signal, i.e., a transmission signal with a frequency of 411 MHz, to obtain multi-channel processed signals.

[0073] Reference Figure 4In some embodiments, the service to be processed is service 1, the antenna includes antenna 1 and antenna 2, the multiple receiving channels may include a first receiving channel 110 and a second receiving channel 120, the first receiving channel 110 includes a first subchannel and a second subchannel, the second receiving channel 120 includes a third subchannel and a fourth subchannel, the first subchannel and the second subchannel of the first receiving channel 110 are both connected to antenna 1, the third subchannel and the fourth subchannel of the second receiving channel 120 are both connected to antenna 2, and the first subchannel, the second subchannel, the third subchannel and the fourth subchannel are RX1, RX2, RX3 and RX4 respectively.

[0074] When service 1 initiates a service with a transmission signal with a frequency of 410 MHz, the first sub-channel RX1 of the first receiving channel 110 is used to receive and process the transmission signal to obtain a first processed signal; the third sub-channel RX3 of the second receiving channel 120 is used to receive and process the transmission signal to obtain a second processed signal, thereby realizing the use of multiple sub-channels RX1 and RX3 on different receiving channels to respectively receive and process the same transmission signal, that is, the transmission signal with a frequency of 410 MHz, to obtain multi-channel processed signals.

[0075] Similarly, when service 1 initiates a service with a transmission signal with a frequency of 411 MHz, the second sub-channel RX2 of the first receiving channel 110 is used to receive and process the transmission signal to obtain a first processed signal; the fourth sub-channel RX4 of the second receiving channel 120 is used to receive and process the transmission signal to obtain a second processed signal, thereby realizing the use of multiple sub-channels RX2 and RX4 on different receiving channels to respectively receive and process the same transmission signal, i.e., the transmission signal with a frequency of 411 MHz, to obtain multi-channel processed signals.

[0076] Or, if Figure 5 As shown, in some embodiments, the number of services to be processed is 2, namely service 1 and service 2, the antenna includes antenna 1 and antenna 2, and the multiple receiving channels may include a first receiving channel 110 and a second receiving channel 120, wherein the first receiving channel 110 includes a first subchannel and a second subchannel, and the second receiving channel 120 includes a third subchannel and a fourth subchannel, the first subchannel and the second subchannel of the first receiving channel 110 are both connected to antenna 1, and the third subchannel and the fourth subchannel of the second receiving channel 120 are both connected to antenna 2, and the first subchannel, the second subchannel, the third subchannel and the fourth subchannel are respectively RX1, RX2, RX3 and RX4.

[0077] When service 1 initiates service with a transmission signal with a frequency of 410 MHz, and service 2 initiates service with a transmission signal with a frequency of 412 MHz, the first sub-channel RX1 in the first receiving channel 110 can be used to receive and process the transmission signal with a frequency of 410 MHz to obtain a first processed signal; and the third sub-channel RX3 in the second receiving channel 120 can be used to receive and process the transmission signal with a frequency of 412 MHz to obtain a second processed signal.

[0078] At the same time, the second subchannel RX2 in the first receiving channel 110 can be used to receive and process the transmission signal with a frequency of 412 MHz to obtain a first processed signal; the fourth subchannel RX4 in the second receiving channel 120 can be used to receive and process the transmission signal with a frequency of 410 MHz to obtain a second processed signal.

[0079] In this way, it is possible to utilize multiple sub-channels on different receiving channels to respectively receive and process the same transmission signal to obtain a multi-path processed signal.

[0080] For another example, in some embodiments, the number of services to be processed is 2, namely service 1 and service 2, the antenna may include antenna 1, antenna 2 and antenna 3, and the multiple receiving channels may include a first receiving channel 110, a second receiving channel 120 and a third receiving channel, wherein the first receiving channel 110 includes a first subchannel and a second subchannel, the second receiving channel 120 includes a third subchannel and a fourth subchannel, the third receiving channel includes a fifth subchannel and a sixth subchannel, the first subchannel and the second subchannel of the first receiving channel 110 are both connected to antenna 1, the third subchannel and the fourth subchannel of the second receiving channel 120 are both connected to antenna 2, and the fifth subchannel and the sixth subchannel of the third receiving channel are both connected to antenna 3.

[0081] When the first service initiates a service with a transmission signal with a frequency of 410 MHz, and the second service initiates a service with a transmission signal with a frequency of 412 MHz, the first sub-channel in the first receiving channel 110 can be used to receive and process the transmission signal with a frequency of 410 MHz to obtain a first processed signal; the third sub-channel in the second receiving channel 120 can be used to receive and process the transmission signal with a frequency of 410 MHz to obtain a second processed signal, and the fifth sub-channel in the third receiving channel can be used to receive and process the transmission signal with a frequency of 410 MHz to obtain a third processed signal.

[0082] Similarly, the second sub-channel in the first receiving channel 110 can be used to receive and process the transmission signal with a frequency of 412 MHz to obtain a first processed signal; the fourth sub-channel in the second receiving channel 120 can be used to receive and process the transmission signal with a frequency of 412 MHz to obtain a second processed signal; and the sixth sub-channel in the third receiving channel can be used to receive and process the transmission signal with a frequency of 412 MHz to obtain a third processed signal.

[0083] In this way, it is possible to utilize multiple sub-channels on different receiving channels to respectively receive and process the same transmission signal to obtain a multi-path processed signal.

[0084] Step 130: Combine the multi-channel processed signals to obtain a target communication signal.

[0085] For example, when the first processed signal and the second processed signal are obtained in step 120, the first processed signal and the second processed signal are combined and processed to obtain the target communication signal.

[0086] When the first processed signal, the second processed signal and the third processed signal are obtained in step 120, the first processed signal, the second processed signal and the third processed signal are combined and processed to obtain the target communication signal.

[0087] This embodiment uses multiple sub-channels on different receiving channels to respectively receive and process the same transmitted signal, so that the transmitted signal can be captured from different angles and paths, which helps to improve the quality of the received signal; secondly, since the signals received by the multiple sub-channels on different receiving channels have different fading characteristics, the present application can reduce the impact of multipath fading by merging and processing multi-channel processed signals, and can also reduce interference on the same receiving channel, that is, reduce interference on the same antenna, thereby improving call quality; in addition, merging and processing multiple signals from different receiving channels can also obtain diversity gain, and diversity gain can improve the sensitivity of the receiver, so that the receiver can operate at a lower signal strength, that is, it can receive signals at a farther distance, thereby improving the communication distance.

[0088] Please refer to the second embodiment of the method for processing communication signals provided in this application. The method includes:

[0089] Step 210: Acquire the transmission signal of the service to be processed.

[0090] Step 220: Determine the quantitative relationship between the services to be processed and the receiving channels.

[0091] Step 230: If the number of services to be processed is less than the number of receiving channels, the first diversity wireless ad hoc network is used to set the frequency of each receiving channel, and multiple sub-channels of the same frequency on different receiving channels are used to respectively receive and process the same transmission signal to obtain a multi-channel processed signal.

[0092] In some implementations, setting the frequencies of the respective receiving channels by using the first diversity wireless ad hoc network in step 230 may include:

[0093] Step 231: According to the frequency information of the transmission signal, at least two receiving channels are set to the same initial frequency.

[0094] In some embodiments, the service to be processed is a first service, a transmission signal of the first service is provided with a first frequency and a second frequency, the multiple receiving channels are a first receiving channel 110 and a second receiving channel 120, the first receiving channel 110 is provided with a first sub-channel and a second sub-channel, the second receiving channel 120 is provided with a third sub-channel and a fourth sub-channel, wherein the first sub-channel and the second sub-channel of the first receiving channel 110 are both connected to antenna 1, and the third sub-channel and the fourth sub-channel of the second receiving channel 120 are both connected to antenna 2.

[0095] Then step 231 may specifically be as follows:

[0096] Step 2311: Set the initial frequencies of the first sub-channel and the third sub-channel to the first frequency.

[0097] Step 2312: Set the initial frequencies of the second sub-channel and the fourth sub-channel to the second frequency.

[0098] For example, Figure 4 As shown, the first service is service 1, the first frequency and the second frequency are 410 MHz and 411 MHz respectively, the first sub-channel, the second sub-channel, the third sub-channel and the fourth sub-channel are RX1, RX2, RX3 and RX4 respectively, then the frequencies of RX1 and RX3 are set to 410 MHz, and the frequencies of RX2 and RX4 are set to 411 MHz.

[0099] Alternatively, in some embodiments, the service to be processed is a first service, a transmission signal of the first service is provided with a first frequency and a second frequency, the antenna may include antenna 1, antenna 2 and antenna 3, and the multiple receiving channels may include a first receiving channel 110, a second receiving channel 120 and a third receiving channel, wherein the first receiving channel 110 and the second receiving channel 120 may include two sub-channels, the first receiving channel 110 includes a first sub-channel and a second sub-channel, the second receiving channel 120 includes a third sub-channel and a fourth sub-channel, the third receiving channel includes a fifth sub-channel and a sixth sub-channel, the first sub-channel and the second sub-channel of the first receiving channel 110 are both connected to antenna 1, the third sub-channel and the fourth sub-channel of the second receiving channel 120 are both connected to antenna 2, and the fifth sub-channel and the sixth sub-channel of the third receiving channel are both connected to antenna 3.

[0100] Then the initial frequencies of the first subchannel, the third subchannel and the fifth subchannel can all be set to the first frequency; the initial frequencies of the second subchannel, the fourth subchannel and the sixth subchannel can all be set to the second frequency. For example, the first service is service 1, the first frequency and the second frequency are 410 MHz and 411 MHz respectively, the first subchannel, the second subchannel, the third subchannel, the fourth subchannel, the fifth subchannel and the sixth subchannel are RX1, RX2, RX3, RX4, RX5 and RX6 respectively, then the frequencies of RX1, RX3 and RX5 are set to 410 MHz, and the frequencies of RX2, RX4 and RX6 are set to 411 MHz, so as to set at least two receiving channels to the same initial frequency.

[0101] For another example, in some embodiments, the number of services to be processed is 2, specifically a first service and a second service, a transmission signal of the first service is provided with a first frequency and a second frequency, a transmission signal of the second service is provided with a third frequency and a fourth frequency, the antenna may include antenna 1, antenna 2 and antenna 3, and a plurality of receiving channels may include a first receiving channel 110, a second receiving channel 120 and a third receiving channel, wherein the first receiving channel 110 and the second receiving channel 120 may include two sub-channels, the first receiving channel 110 includes a first sub-channel and a second sub-channel, the second receiving channel 120 includes a third sub-channel and a fourth sub-channel, the third receiving channel includes a fifth sub-channel and a sixth sub-channel, the first sub-channel and the second sub-channel of the first receiving channel 110 are both connected to antenna 1, the third sub-channel and the fourth sub-channel of the second receiving channel 120 are both connected to antenna 2, and the fifth sub-channel and the sixth sub-channel of the third receiving channel are both connected to antenna 3.

[0102] Then, the initial frequencies of the first subchannel and the third subchannel can be set to the first frequency; the initial frequencies of the second subchannel and the fourth subchannel can be set to the second frequency, the initial frequency of the fifth subchannel can be set to the third frequency; and the initial frequency of the sixth subchannel can be set to the fourth frequency, so as to set at least two receiving channels to the same initial frequency.

[0103] Step 240: If the number of services to be processed is equal to the number of receiving channels, the second diversity wireless ad hoc network is used to set the frequency of each receiving channel, and multiple sub-channels of the same frequency on different receiving channels are used to respectively receive and process the same transmission signal to obtain a multi-channel processed signal.

[0104] In some implementations, setting the frequencies of the respective receiving channels using the second diversity wireless ad hoc network in step 240 may include the following:

[0105] Step 241: according to the frequency information of the transmission signal, multiple sub-channels on different receiving channels are set to different initial frequencies, wherein the initial frequency of each receiving channel is the same as the available frequency of the corresponding service to be processed.

[0106] For example, in some embodiments, the number of services to be processed is 2, specifically a first service and a second service, a transmission signal of the first service is provided with available frequencies of a first frequency and a second frequency, a transmission signal of the second service is provided with available frequencies of a third frequency and a fourth frequency, the antenna may include antenna 1 and antenna 2, a plurality of receiving channels may include a first receiving channel 110 and a second receiving channel 120, wherein the first receiving channel 110 and the second receiving channel 120 may include two sub-channels, the first receiving channel 110 includes a first sub-channel and a second sub-channel, the second receiving channel 120 includes a third sub-channel and a fourth sub-channel, the first sub-channel and the second sub-channel of the first receiving channel 110 are both connected to antenna 1, and the third sub-channel and the fourth sub-channel of the second receiving channel 120 are both connected to antenna 2.

[0107] The initial frequency of the first subchannel can be set to the first frequency, and the initial frequency of the second subchannel can be set to the second frequency; the initial frequency of the third subchannel can be set to the third frequency; and the initial frequency of the fourth subchannel can be set to the fourth frequency, that is, the first subchannel and the second subchannel of the first receiving channel 110 correspond to the first frequency and the second frequency of the first business respectively, and the third subchannel and the fourth subchannel of the second receiving channel 120 correspond to the third frequency and the fourth frequency of the second business respectively, so as to set multiple subchannels on different receiving channels to different initial frequencies.

[0108] Exemplarily, the first service and the second service are service 1 and service 2 respectively, the first frequency, the second frequency, the third frequency and the fourth frequency are 410 MHz, 411 MHz, 412 MHz and 413 MHz respectively, the first sub-channel, the second sub-channel, the third sub-channel and the fourth sub-channel are RX1, RX2, RX3 and RX4 respectively, then the frequencies of RX1, RX2, RX3 and RX4 are set to 410 MHz, 411 MHz, 412 MHz and 413 MHz respectively.

[0109] For another example, in some embodiments, the number of services to be processed is 3, specifically a first service, a second service, and a third service. The transmission signal of the first service is provided with a first frequency and a second frequency, the transmission signal of the second service is provided with a third frequency and a fourth frequency, and the transmission signal of the third service is provided with a fifth frequency and a sixth frequency. The antenna may include antenna 1, antenna 2, and antenna 3. The multiple receiving channels may include a first receiving channel 110, a second receiving channel 120, and a third receiving channel, wherein the first receiving channel 110 includes a first subchannel and a second subchannel, the second receiving channel 120 includes a third subchannel and a fourth subchannel, and the third receiving channel includes a fifth subchannel and a sixth subchannel. The first subchannel and the second subchannel of the first receiving channel 110 are both connected to antenna 1, the third subchannel and the fourth subchannel of the second receiving channel 120 are both connected to antenna 2, and the fifth subchannel and the sixth subchannel of the third receiving channel are both connected to antenna 3.

[0110] The initial frequency of the first subchannel can be set to the first frequency, and the initial frequency of the second subchannel can be set to the second frequency; the initial frequency of the third subchannel can be set to the third frequency; the initial frequency of the fourth subchannel can be set to the fourth frequency; the initial frequency of the fifth subchannel can be set to the fifth frequency; and the initial frequency of the sixth subchannel can be set to the sixth frequency, that is, the first subchannel and the second subchannel of the first receiving channel 110 correspond to the first frequency and the second frequency of the first business respectively, and the third subchannel and the fourth subchannel of the second receiving channel 120 correspond to the third frequency and the fourth frequency of the second business respectively, and the fifth subchannel and the sixth subchannel of the third receiving channel correspond to the fifth frequency and the sixth frequency of the third business respectively, so as to set multiple subchannels on different receiving channels to different initial frequencies.

[0111] Exemplarily, the first service, the second service and the third service are service 1, service 2 and service 3 respectively, the first frequency, the second frequency, the third frequency, the fourth frequency, the fifth frequency and the sixth frequency are 410 MHz, 411 MHz, 412 MHz, 413 MHz, 414 MHz and 415 MHz respectively, the first sub-channel, the second sub-channel, the third sub-channel, the fourth sub-channel, the fifth sub-channel and the sixth sub-channel are RX1, RX2, RX3, RX4, RX5 and RX6 respectively, then the frequencies of RX1, RX2, RX3, RX4, RX5 and RX6 can be set to 410 MHz, 411 MHz, 412 MHz, 413 MHz, 414 MHz and 415 MHz respectively, so as to set multiple sub-channels on different receiving channels to different initial frequencies.

[0112] Step 250: Combine the multi-channel processed signals to obtain a target communication signal.

[0113] Step 250 has the same or similar implementation as step 130 in the first embodiment, and will not be described in detail herein.

[0114] In some embodiments, after each receiving channel of different antennas is set to a different initial frequency in step 241, the following steps may also be included:

[0115] Step 341: The subchannel receiving the transmission signal in each receiving channel is used as the target subchannel, and the remaining subchannels are used as idle subchannels.

[0116] For example, in some embodiments, the number of services to be processed is 2, specifically the first service and the second service, the transmission signal of the first service is provided with a first frequency of 410 MHz and a second frequency of 411 MHz, the transmission signal of the second service is provided with a third frequency of 412 MHz and a fourth frequency of 413 MHz, the antenna may include antenna 1 and antenna 2, the multiple receiving channels may include a first receiving channel 110 and a second receiving channel 120, wherein the first receiving channel 110 includes a first sub-channel and a second sub-channel, the second receiving channel 120 includes a third sub-channel and a fourth sub-channel, the first sub-channel and the second sub-channel of the first receiving channel 110 are both connected to antenna 1, and the third sub-channel and the fourth sub-channel of the second receiving channel 120 are both connected to antenna 2. And the initial frequencies of the first sub-channel, the second sub-channel, the third sub-channel and the fourth sub-channel are 410 MHz, 411 MHz, 412 MHz and 413 MHz respectively.

[0117] When the first service initiates a call at a target frequency, such as the first frequency 410 MHz, the subchannel in the receiving channel with the same frequency as the target frequency (such as the first subchannel) is used as the target subchannel, and the remaining subchannels in the first service (such as the second subchannel) are used as idle subchannels.

[0118] Similarly, when the second service initiates a call with a target frequency, such as the third frequency 412 MHz, the subchannel in the receiving channel with the same frequency as the target frequency (such as the third subchannel) is used as the target subchannel, and the remaining subchannels in the second service (such as the fourth subchannel) are used as idle subchannels.

[0119] For example, see Figure 1 and Figure 5 The first service and the second service are service 1 and service 2 respectively, the first sub-channel, the second sub-channel, the third sub-channel and the fourth sub-channel are RX1, RX2, RX3 and RX4 respectively, and the corresponding initial frequencies are 410 MHz, 411 MHz, 412 MHz and 413 MHz respectively.

[0120] When service 1 initiates a call at 410 MHz, since the frequency of RX1 in the first receiving channel 110 is the same as 410 MHz, RX1 in the first receiving channel 110 is used as the target sub-channel and RX2 in the first receiving channel 110 is used as the idle sub-channel.

[0121] Similarly, when service 2 initiates a call at 412 MHz, since the frequency of RX3 in the second receiving channel 120 is the same as 412 MHz, RX3 in the second receiving channel 120 is used as the target sub-channel and RX4 in the second receiving channel 120 is used as the idle sub-channel.

[0122] Step 342: After the pending service initiates a call at the target frequency, if other pending services initiate calls, the initial frequencies of the idle subchannels in the other pending services are adjusted to the same frequency as the target subchannel in the pending service.

[0123] For example, when the first service initiates a call with a target frequency such as the first frequency 410 MHz, the first subchannel in the first service (initial frequency is 410 MHz) is used as the target subchannel, and the second subchannel in the first service (initial frequency is 411 MHz) is used as the idle subchannel.

[0124] If the second service initiates a call with a target frequency, such as the third frequency 412MHz, the third subchannel in the second service (with an initial frequency of 412MHz) is used as the target subchannel, and the fourth subchannel in the second service (with an initial frequency of 413MHz) is used as the idle subchannel. The initial frequency 411MHz of the idle subchannel in the first service, i.e., the second subchannel, is adjusted to the frequency of the target subchannel of the second service, i.e., 412MHz, and the initial frequency 413MHz of the idle subchannel in the second service, i.e., the fourth subchannel, is adjusted to the frequency of the target subchannel of the first service, i.e., 410MHz, so as to adjust the initial frequency of the idle subchannel in the service to be processed to the same frequency as the target subchannel in other services to be processed.

[0125] Combination Figure 1 and Figure 5 As shown, when service 1 initiates a call at 410 MHz and service 2 initiates a call at 412 MHz, RX1 in the first receiving channel 110 serves as the target sub-channel, RX2 in the first receiving channel 110 serves as the idle sub-channel, RX3 in the second receiving channel 120 serves as the target sub-channel, and RX4 in the second receiving channel 120 serves as the idle sub-channel.

[0126] Then the initial frequency 411 MHz of the idle sub-channel RX2 in service 1 is adjusted to 412 MHz, and the initial frequency 413 MHz of the idle sub-channel RX4 in service 2 is adjusted to 410 MHz.

[0127] In this way, the target subchannel of the first service (i.e., the first subchannel) and the idle subchannel after the frequency is adjusted in the second service, i.e., the fourth subchannel, can be used to respectively receive and process the transmission signal of the first frequency 410 MHz of the first service; and the target subchannel of the second service (i.e., the third subchannel) and the idle subchannel after the frequency is adjusted in the first service, i.e., the second subchannel, can be used to respectively receive and process the transmission signal of the third frequency 412 MHz of the second service.

[0128] Similarly, when the first service initiates a call with a target frequency, such as the second frequency 411 MHz, the second subchannel in the first service (initial frequency is 411 MHz) is used as the target subchannel, and the first subchannel in the first service (initial frequency is 410 MHz) is used as the idle subchannel.

[0129] When the second service initiates a call with a target frequency, such as the third frequency 412MHz, the third subchannel (initial frequency is 412MHz) in the second service is used as the target subchannel, and the fourth subchannel (initial frequency is 413MHz) in the second service is used as the idle subchannel. The initial frequency 410MHz of the idle subchannel in the first service, i.e., the first subchannel, is adjusted to the frequency of the target subchannel of the second service, i.e., 412MHz, and the initial frequency 413MHz of the idle subchannel in the second service, i.e., the fourth subchannel, is adjusted to the frequency of the target subchannel of the first service, i.e., 411MHz, so as to adjust the initial frequency of the idle subchannel in the service to be processed to the same frequency as the target subchannel in other services to be processed.

[0130] In this way, the target subchannel of the first service (i.e., the second subchannel) and the idle subchannel after the frequency is adjusted in the second service, i.e., the fourth subchannel, can be used to respectively receive and process the transmission signal of the first frequency 411 MHz of the first service; and the target subchannel of the second service (i.e., the third subchannel) and the idle subchannel after the frequency is adjusted in the first service, i.e., the first subchannel, can be used to respectively receive and process the transmission signal of the third frequency 412 MHz of the second service.

[0131] Alternatively, when the first service initiates a call with a target frequency, such as the second frequency 411 MHz, the second subchannel in the first service (initial frequency is 411 MHz) is used as the target subchannel, and the first subchannel in the first service (initial frequency is 410 MHz) is used as the idle subchannel.

[0132] When the second service initiates a call with a target frequency, such as the fourth frequency 413MHz, the fourth subchannel (initial frequency is 413MHz) in the second service is used as the target subchannel, and the third subchannel (initial frequency is 412MHz) in the second service is used as the idle subchannel. The initial frequency 410MHz of the idle subchannel in the first service, i.e., the first subchannel, is adjusted to the frequency of the target subchannel of the second service, i.e., 413MHz, and the initial frequency 412MHz of the idle subchannel in the second service, i.e., the third subchannel, is adjusted to the frequency of the target subchannel of the first service, i.e., 411MHz, so as to adjust the initial frequency of the idle subchannel in the service to be processed to the same frequency as the target subchannel in other services to be processed.

[0133] In this way, the target subchannel of the first service (i.e., the second subchannel) and the idle subchannel after the frequency is adjusted in the second service, i.e., the third subchannel, can be used to respectively receive and process the transmission signal of the first frequency 411 MHz of the first service; and the target subchannel of the second service (i.e., the fourth subchannel) and the idle subchannel after the frequency is adjusted in the first service, i.e., the first subchannel, can be used to respectively receive and process the transmission signal of the fourth frequency 413 MHz of the second service.

[0134] In some embodiments, after the initial frequency of the idle subchannel in the pending service is adjusted to the same frequency as the target subchannel in other pending services, the adjusted frequency may be switched back to the initial frequency to wait for the initiation of other frequency signals in the pending service. For details, please refer to the following steps:

[0135] Step 343: When the service to be processed ends the call, the frequency of the idle sub-channel is adjusted to the initial frequency.

[0136] For example, in step 341-step 342, the initial frequencies of the first subchannel, the second subchannel, the third subchannel and the fourth subchannel are 410MHz, 411MHz, 412MHz and 413MHz respectively. When the first service initiates a call with a target frequency, such as the second frequency 411MHz, and the second service initiates a call with a target frequency, such as the third frequency 412MHz, and the initial frequency 410MHz of the idle subchannel in the first service, i.e., the first subchannel, is adjusted to 412MHz, and the initial frequency 413MHz of the idle subchannel in the second service, i.e., the fourth subchannel, is adjusted to 411MHz, if the first service ends the call, the idle subchannel in the first service, i.e., the first subchannel, at this time, is adjusted from 412MHz to the initial frequency 410MHz for waiting.

[0137] If the second service ends the call, the idle sub-channel in the second service, that is, the frequency of the fourth sub-channel at this time, 411 MHz, is adjusted to the initial frequency 413 MHz for waiting.

[0138] Please refer to the third embodiment of the method for processing a communication signal provided in this application. The method includes:

[0139] Step 410: Acquire the transmission signal of the service to be processed.

[0140] Step 420: Utilize multiple sub-channels on different receiving channels to respectively receive and process the same transmission signal to obtain a multi-channel processed signal.

[0141] Step 430: Change the delivery addresses of multiple receiving channels that receive the same transmission signal to the same delivery address.

[0142] Step 440: Based on the delivery address, the multi-channel processed signals are input into the same target digital signal processor for merging processing.

[0143] For step 430-step 440, in some embodiments, for example, the software processing unit 200 may include a first digital signal processor, a second digital signal processor and a third digital signal processor, the service to be processed is a first service, the antenna includes antenna 1, antenna 2 and antenna 3, the multiple receiving channels are a first receiving channel 110, a second receiving channel 120 and a third receiving channel, and the first receiving channel 110, the second receiving channel 120 and the third receiving channel each have only one subchannel; the input end of the subchannel of the first receiving channel 110 is connected to antenna 1, and the output end of the subchannel of the first receiving channel 110 is connected to the first digital signal processor; the input end of the subchannel of the second receiving channel 120 is connected to antenna 2, the output end of the subchannel of the second receiving channel 120 is connected to the second digital signal processor, the input end of the subchannel of the third receiving channel is connected to antenna 3, and the output end of the subchannel of the third receiving channel is connected to the third digital signal processor.

[0144] When the first service initiates a service with a transmission signal with a frequency of 410 MHz, the sub-channel of the first receiving channel 110 is used to receive and process the transmission signal with a frequency of 410 MHz to obtain a first processed signal; the sub-channel of the second receiving channel 120 is used to receive and process the transmission signal with a frequency of 410 MHz to obtain a second processed signal, and the sub-channel of the third receiving channel is used to receive and process the transmission signal with a frequency of 410 MHz to obtain a third processed signal.

[0145] Since the output end of the subchannel of the first receiving channel 110 is connected to the first digital signal processor, the output end of the subchannel of the second receiving channel 120 is connected to the second digital signal processor, and the output end of the subchannel of the third receiving channel is connected to the third digital signal processor.

[0146] Therefore, the distribution address of the subchannel of the first receiving channel 110 itself is the address of the first digital signal processor, the original distribution address of the subchannel of the second receiving channel 120 should be the address of the second digital signal processor, and the original distribution address of the subchannel of the third receiving channel should be the address of the third digital signal processor. However, since the subchannels of the first receiving channel 110, the subchannels of the second receiving channel 120 and the subchannels of the third receiving channel all receive and process the transmission signal with a frequency of 410 MHz, in order to input the first processed signal, the second processed signal and the third processed signal into the same target digital signal processor (i.e., the first digital signal processor) for merge processing, it is necessary to change the distribution addresses of the subchannels of the second receiving channel 120 and the subchannels of the third receiving channel to the same distribution address as the subchannels of the first receiving channel 110, i.e., the address of the first digital signal processor.

[0147] For another example, in some embodiments, the software processing unit 200 includes a first digital signal processor and a second digital signal processor, the service to be processed is a first service, the antenna includes an antenna 1 and an antenna 2, the multiple receiving channels are a first receiving channel 110 and a second receiving channel 120, the first receiving channel 110 is provided with a first sub-channel and a second sub-channel, the input ends of the first sub-channel and the second sub-channel are both connected to the antenna 1, and the output ends of the first sub-channel and the second sub-channel are both connected to the first digital signal processor;

[0148] The second receiving channel 120 is provided with a third sub-channel and a fourth sub-channel, the input ends of the third sub-channel and the fourth sub-channel are both connected to the antenna 2, and the output ends of the third sub-channel and the fourth sub-channel are both connected to the second digital signal processor.

[0149] When the first service initiates the service with a transmission signal of a frequency of 410 MHz, the first sub-channel is used to receive and process the transmission signal to obtain a first processed signal; the third sub-channel is used to receive and process the transmission signal to obtain a second processed signal, and the distribution address of the first processed signal is the address of the first digital signal processor, and the original distribution address of the second processed signal is the address of the second digital signal processor. Therefore, in order to input both the first processed signal and the second processed signal into the same target digital signal processor (i.e., the first digital signal processor) for combined processing, the original distribution address of the second processed signal is changed to the same distribution address as the first processed signal, i.e., the address of the first digital signal processor.

[0150] For another example, the software processing unit 200 includes a first digital signal processor and a second digital signal processor, the services to be processed are a first service and a second service, the antenna includes an antenna 1 and an antenna 2, the multiple receiving channels are a first receiving channel 110 and a second receiving channel 120, the first receiving channel 110 is provided with a first sub-channel and a second sub-channel, the input ends of the first sub-channel and the second sub-channel are both connected to the antenna 1, and the output ends of the first sub-channel and the second sub-channel are both connected to the first digital signal processor; the second receiving channel 120 is provided with a third sub-channel and a fourth sub-channel, the input ends of the third sub-channel and the fourth sub-channel are both connected to the antenna 2, and the output ends of the third sub-channel and the fourth sub-channel are both connected to the second digital signal processor.

[0151] When the first service initiates the service with a transmission signal of a frequency of 410MHz, and the second service initiates the service with a transmission signal of a frequency of 413MHz, the transmission signal of the frequency of 410MHz is received and processed by the first sub-channel to obtain the first processed signal; the transmission signal of the frequency of 410MHz is received and processed by the third sub-channel to obtain the third processed signal. The transmission signal of the frequency of 413MHz is received and processed by the second sub-channel to obtain the second processed signal; the transmission signal of the frequency of 413MHz is received and processed by the fourth sub-channel to obtain the fourth processed signal.

[0152] Since the output ends of the first sub-channel and the second sub-channel are both connected to the first digital signal processor; the output ends of the third sub-channel and the fourth sub-channel are both connected to the second digital signal processor.

[0153] Therefore, the distribution address of the first processed signal and the second processed signal itself should be the address of the first digital signal processor, and the distribution address of the third processed signal and the fourth processed signal itself should be the address of the second digital signal processor. However, since the third subchannel and the first subchannel both receive and process the transmission signal with a frequency of 410 MHz, it is necessary to change the distribution address of the third subchannel and the first subchannel to the same distribution address, that is, change the distribution address of the third subchannel from the original address of the second digital signal processor to the address of the first digital signal processor, so that the first processed signal and the third processed signal can be input into the first digital signal processor for combined processing.

[0154] Similarly, since the second subchannel and the fourth subchannel both receive and process transmission signals with a frequency of 413 MHz, it is necessary to change the distribution addresses of the second subchannel and the fourth subchannel to the same distribution address, that is, change the distribution address of the second subchannel from the original address of the first digital signal processor to the address of the second digital signal processor, so that the second processed signal and the fourth processed signal can be input into the second digital signal processor for combined processing.

[0155] In some embodiments, the multi-channel processed signals can be input into the FPGA respectively to edit and change the delivery address, and then the changed processed signals can be input into the corresponding target digital signal processor for combined processing.

[0156] Referring to the fourth embodiment of the method for processing a communication signal provided by the present application, the method includes:

[0157] Step 510: Acquire a transmission signal of a service to be processed, where the service to be processed includes a first service and a second service.

[0158] Step 520: Determine whether the received bit error rates of the first service and the second service are both less than or equal to a first threshold.

[0159] The first threshold may be 5%.

[0160] Step 530: If yes, a conventional wireless ad hoc network is used to process the transmission signal of the service to be processed.

[0161] Step 540: If not, determine whether the received bit error rates of the first service and the second service are both greater than or equal to the second threshold.

[0162] The second threshold may be 10%.

[0163] Step 550: If yes, switch the conventional wireless ad hoc network to the first diversity wireless ad hoc network.

[0164] For step 520 to step 550, that is, when the receiving bit error rates of the first service and the second service are both ≤5%, the conventional wireless ad hoc network is used to process the transmission signal of the service to be processed; when the receiving bit error rates of the first service and the second service are both ≥10%, that is, the receiving bit error rates of the two services are too high, and only one of the services can be discarded, that is, Figure 1 The conventional wireless ad hoc network shown is switched to Figure 4 The first diversity wireless ad hoc network is shown.

[0165] Among them, the specific values ​​of the first threshold and the second threshold can be flexibly set according to the system communication requirements, and this application does not impose any restrictions on this.

[0166] Combination Figure 1 and Figure 4 , you can Figure 1 The initial frequencies of the subchannels RX1, RX2, RX3 and RX4 are adjusted from 410 MHz, 411 MHz, 412 MHz and 413 MHz to 410 MHz for RX1 and RX3 and 411 MHz for RX2 and RX4, thereby switching from a conventional wireless ad hoc network to a first diversity wireless ad hoc network.

[0167] When the bit error rates of the two services are between 5% and 10%, the current state can be maintained without switching.

[0168] In this way, by judging the receiving bit error rates of the two services, it is possible to flexibly choose to configure the conventional wireless ad hoc network and the first diversity wireless ad hoc network. When two groups of services are needed and the receiving bit error rates of the two groups of services are relatively low, a conventional wireless ad hoc network can be configured. When the receiving bit error rates of the two services are relatively high, the first diversity wireless ad hoc network can be configured, thereby achieving flexible switching between the two modes.
