Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a microwave communication system and a microwave device. Background Art

[0002] As the demand for services in wireless communication systems grows, the capacity of long-distance microwave transmission services is also increasing, requiring more spectrum channels for service transmission. Currently, the carrier signals of each spectrum channel are sent using the same antenna after being combined, and the receiving end uses two antennas for reception, which can solve the problem of multipath fading.

[0003] Although sending the combined carrier signal through one antenna and then receiving the combined signal through two antennas can solve the problem of multipath fading to a certain extent, combining multiple carrier signals during transmission will cause serious combining loss, thereby affecting the gain of the microwave communication system. Summary of the invention

[0004] The present application provides a microwave communication system and a microwave device, which are used to reduce the combining loss when the microwave communication system transmits a carrier signal and improve the gain of the microwave communication system.

[0005] In a first aspect, the present application provides a microwave communication system, comprising: a first device and a second device, the first device comprising multiple antennas, and the second device comprising multiple antennas; the first device is used to send carrier signals of at least two frequencies through at least two antennas among the multiple antennas, and each of the at least two antennas corresponds to a carrier signal of at least one frequency; the second device is used to receive carrier signals of at least two frequencies through at least two antennas among the multiple antennas, wherein each of the at least two antennas receives carrier signals of at least two frequencies.

The microwave communication system can be a system composed of microwave devices through microwave communication, or it can be a communication system including microwave devices, access network devices, core networks, and terminal devices.

[0008] In the present application, sending carrier signals of at least two frequencies through at least two antennas may be one antenna sending a carrier signal of one frequency. If there are more carrier signals of different frequencies and fewer antennas, each antenna may also send two or more carrier signals of different frequencies.

[0009] In the present application, each antenna of the second device receives carrier signals of at least two frequencies means that each antenna of the second device receives all carrier signals sent by the first device.

[0010] The present application provides a microwave communication system, in which at the transmitting end, at least two frequency points of carrier signals are transmitted through at least two antennas, so that the transmitting end does not need to transmit all carrier signals through one antenna, so there is no need for power backoff, or the carrier signal can be transmitted by backing off a smaller power, thereby reducing the combining loss when the microwave communication system transmits the carrier signal. In addition, each of the multiple antennas at the receiving end receives all the carrier signals transmitted by the transmitting end, and each antenna receives the same signal, which has spatial diversity capability and improves the signal gain of the microwave communication system.

[0016] In this possible implementation, one polarization type may be understood as not performing polarization processing on the carrier signal.

[0017] In a possible implementation, in a dual-polarization scenario, each antenna corresponds to two polarization types of transceiver lines.

[0018] In this possible implementation, the two polarization types may be polarization processing performed on the carrier signal in the horizontal direction and the vertical direction, or polarization processing performed on the carrier signal in the direction of +45° or -45°.

[0026] In this possible implementation, the distance between the third transceiver line and the fourth transceiver line is less than the second threshold value, which can reduce the use of RF cables. The receiving unit of the third transceiver line and the receiving unit of the fifth transceiver line are connected through an intermediate frequency cable or a digital cable, and carrier signals of different polarization directions of the same frequency can be transmitted to the same antenna without the need for mutual transmission of RF cables, thereby reducing the use of RF cables and reducing the insertion loss caused by the use of longer RF cables.

[0027] In a possible implementation, each transceiver line includes a radio frequency segment, an analog intermediate frequency segment, and a digital baseband segment, and the combining unit is located in the analog intermediate frequency segment or the digital baseband segment.

[0046] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all embodiments. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0047] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] The embodiments of the present application provide a microwave communication system and a microwave device, which are used to reduce the combining loss when the microwave communication system transmits carrier signals and improve the gain of the microwave communication system.

[0049] To facilitate understanding of the embodiments of the present application, the following first briefly introduces the terms involved in the present application.

[0050] 1. Microwave communication: refers to electromagnetic waves with a wavelength between 0.1 and 1 meter and a frequency range of 300MHz to 3000GHz. Microwaves are used as carrier waves to carry information and conduct relay communications. Unlike modern communication network transmission methods such as coaxial cable communication, optical fiber communication and satellite communication, microwave communication directly uses microwaves as a medium for communication. It does not require solid media and can be transmitted using microwaves when there is no obstacle within the straight-line distance between two points. Using microwaves for communication has the characteristics of large capacity, good quality and can be transmitted over long distances.

[0051] 2. Antenna: Antenna is an indispensable component in mobile communication and plays a very important role. Antenna is located between the transceiver and the electromagnetic wave propagation space, and realizes effective energy transfer between the two. By designing the radiation characteristics of the antenna, the spatial distribution of electromagnetic energy can be controlled, resource utilization can be improved, and network quality can be optimized. Due to the propagation environment, the carrier signal will produce deep fading and Doppler frequency shift, etc., causing the receiving level to drop to near the thermal noise level, and the phase will also change randomly over time, resulting in a decrease in communication quality. In this regard, diversity reception technology can be used to reduce the impact of fading, obtain diversity gain, and improve receiving sensitivity. Diversity antennas include spatial diversity, directional diversity, polarization diversity, and field component diversity.

[0052] 3. Space diversity (SD): SD is also called antenna diversity. It is achieved by using multiple receiving antennas. It uses receiving antennas at different locations for diversity reception. It is one of the diversity forms used in wireless communications. The basic principle of diversity is to receive multiple copies of the same information through multiple channels (time, frequency or space). Due to the different transmission characteristics of multiple channels, the fading of multiple copies of the signal will not be the same. The receiver can use the information contained in multiple copies to more accurately restore the original transmitted signal. If diversity technology is not used, under noise-limited conditions, the transmitter must send higher power to ensure normal link connection when the channel conditions are poor.

[0053] 4. Baseband: Baseband is used to realize signal modulation and demodulation.

[0079] The antenna 201 receives a carrier signal 301 of a first frequency and a carrier signal 302 of a second frequency, and then the antenna 201 transmits the carrier signal 301 of the first frequency and the carrier signal 302 of the second frequency to the transceiver control unit 2034, the transceiver control unit 2034 transmits the carrier signal 301 of the first frequency and the carrier signal 302 of the second frequency to the receiving unit 2033, the receiving unit 2033 transmits the carrier signal 301 of the first frequency and the carrier signal 302 of the second frequency to the combining unit 205, the combining unit 205 can separate the carrier signal 301 of the first frequency and the carrier signal 302 of the second frequency, transmit the carrier signal 301 of the first frequency to the baseband 2031 for demodulation, and transmit the carrier signal 302 of the second frequency to the baseband 2041 for demodulation.

[0081] The above description is about the communication process in which the first device 100 acts as a transmitter and the second device 200 acts as a receiver. Conversely, if the second device 200 acts as a transmitter and the first device 100 acts as a receiver, the above process can also be referred to, except that the sending process occurs in the second device 200 and the receiving process is sent in the first device 100.

[0082] In the embodiment of the present application, the transmission of carrier signals of different frequencies to the antenna is achieved through the transceiver line, and the separation of carrier signals of at least two frequencies on each transceiver line is achieved through the combining unit, which can reduce the combining loss in the transmission process and improve the signal gain in the receiving process.

[0083] The solution provided in the embodiment of the present application can be applied to single polarization scenarios or dual polarization scenarios. In single polarization scenarios, each antenna corresponds to a transceiver line of one polarization type. Figure 3 To understand it, during the transmission process, the carrier signal is not polarized, and each antenna can correspond to one transceiver line.

[0084] In the embodiment of the present application, in the dual-polarization scenario, each antenna corresponds to two polarization types of transceiver lines. The two polarization types can be polarization processing of the carrier signal in the horizontal direction and the vertical direction, or polarization processing of the carrier signal in the direction of +45° or -45°.

[0085] In a dual-polarization scenario, multiple transceiver lines are included in at least two line groups, wherein each line group includes at least two transceiver lines, and at least two transceiver lines in the same line group share a combining unit; the transceiver lines in the same line group are used to send carrier signals of different frequencies in the same polarization direction, or to receive carrier signals of at least two frequencies in the same polarization direction; the polarization directions of carrier signals on transceiver lines in different line groups are different.

[0086] Among them, at least two line groups include a first line group and a second line group, the first line group includes a first transceiver line, and the second line group includes a second transceiver line; a cross-polarization interference canceller is arranged between the baseband of the first transceiver line and the baseband of the second transceiver line; the antennas corresponding to the first transceiver line and the second transceiver line are configured with polarization separators, and the polarization separators are respectively connected to the first transceiver line and the second transceiver line through radio frequency cables, and the distance between the first transceiver line and the second transceiver line is greater than a first threshold; the carrier signals sent on the first transceiver line and the second transceiver line have the same frequency and different polarization directions; the polarization directions of the carrier signals of at least two frequency points received on the first transceiver line and the second transceiver line are different.

[0087] The structure and communication process of the microwave device in the dual polarization scenario can be found in the following Figure 4 To understand.

[0088] like Figure 4 As shown, the microwave communication system includes a first device 100 and a second device 200, and the first device 100 includes an antenna 101 and an antenna 102, and a line group 1 and a line group 2. Among them, the line group 1 includes a transceiver line 103 and a transceiver line 104, and the line group 2 includes a transceiver line 106 and a transceiver line 107. The transceiver line 103 and the transceiver line 104 share a combining unit 105, and the transceiver line 106 and the transceiver line 107 share a combining unit 108. Among them, a cross-polarization interference counteracter (XPIC) is arranged between the baseband 1031 and the baseband 1061, and a cross-polarization interference counteracter is arranged between the baseband 1041 and the baseband 1071. Figure 4In the illustrated architecture, a polarization separator (orthomode transducer, OMT) 1011 is installed on the antenna 101, and the antenna 101 is connected to the transceiver line 103 and the transceiver line 106 through the polarization separator 1011 through the radio frequency cable, and a polarization separator 1021 is installed on the antenna 102, and the antenna 102 is connected to the transceiver line 104 and the transceiver line 107 through the radio frequency cable through the polarization separator 1021. In order to reduce the multipath effect, the distance between the antenna 101 and the antenna 102 is usually large, such as: greater than 10 meters, so the radio frequency cable connecting the antenna 101 and the transceiver line 106, and the radio frequency cable connecting the antenna 102 and the transceiver line 104 are usually long.

[0089] Similarly, the second device 200 Figure 4 Four transceiver lines are also shown, among which the transceiver line 203 and the transceiver line 204 belong to a line group and share a combiner unit 205. The transceiver line 206 and the transceiver line 207 belong to a line group and share a combiner unit 208. A cross-polarization interference canceller is provided between the baseband 2031 and the baseband 2061, and a cross-polarization interference canceller is provided between the baseband 2041 and the baseband 2071. A polarization separator 2011 is installed on the antenna 201, and the antenna 201 is connected to the transceiver line 203 and the transceiver line 206 through a radio frequency cable via the polarization separator 2011. A polarization separator 2021 is installed on the antenna 202, and the antenna 202 is connected to the transceiver line 204 and the transceiver line 207 through a radio frequency cable via the polarization separator 2021. The radio frequency cable connecting the antenna 201 and the transceiver circuit 206 , and the radio frequency cable connecting the antenna 202 and the transceiver circuit 204 are usually long, for example, longer than 10 meters.

[0090] For details about the units and connections on each receiving and transmitting line, please refer to Figure 3 Part of the introduction, combined with Figure 4 For your understanding, we will not introduce them one by one here.

[0091] In the above dual-polarization scenario, the carrier signal transmission and reception process may be:

[0092] The baseband 1031 processes the carrier signal 301 of the first frequency point into a carrier signal 3011 of the first direction (e.g., horizontal), and the baseband 1061 processes the carrier signal 301 of the first frequency point into a carrier signal 3012 of the second direction (e.g., vertical). Then, the carrier signal 3011 of the first direction is transmitted in the transceiver line 103, and is transmitted to the polarization separator 1011 through a shorter RF cable, and the carrier signal 3012 of the second direction is transmitted in the transceiver line 106, and is transmitted to the polarization separator 1011 through a longer RF cable. Then, the antenna 101 transmits the carrier signal 3011 of the first frequency point in the first direction and the carrier signal 3012 in the second direction.

[0093] Similarly, the baseband 1041 processes the carrier signal 302 of the second frequency point into a carrier signal 3021 in a first direction (e.g., horizontally), and the baseband 1071 processes the carrier signal 302 of the second frequency point into a carrier signal 3022 in a second direction (e.g., vertically). Then, the carrier signal 3021 in the first direction is transmitted in the transceiver line 104, and is transmitted to the polarization separator 1021 through a shorter RF cable, and the carrier signal 3022 in the second direction is transmitted in the transceiver line 107, and is transmitted to the polarization separator 1021 through a longer RF cable. Then, the antenna 102 transmits the carrier signal 3021 of the second frequency point in the first direction and the carrier signal 3022 in the second direction.

[0094] Correspondingly, antenna 201 and antenna 202 of the second device will receive four carrier signals, namely: carrier signal 3011 of the first frequency in the first direction and carrier signal 3012 in the second direction, and carrier signal 3021 of the second frequency in the first direction and carrier signal 3022 in the second direction.

[0095] The polarization separator 2011 corresponding to the antenna 201 will transmit the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction to the transceiver line 203, and transmit the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction to the transceiver line 206.

[0096] The polarization separator 2021 corresponding to the antenna 202 will transmit the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction to the transceiver line 204, and transmit the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction to the transceiver line 207.

[0097] The combining unit 205 separates the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction on the transceiver line 203 and the transceiver line 204, and demodulates the carrier signal 3011 by the baseband 2031 and demodulates the carrier signal 3021 by the baseband 2041.

[0098] The combining unit 208 separates the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction on the transceiver line 206 and the transceiver line 207, and the baseband 2061 demodulates the carrier signal 3012 and the baseband 2071 demodulates the carrier signal 3022.

[0099] Each of the above-mentioned transceiver lines includes a radio frequency segment, an analog intermediate frequency segment, and a digital baseband segment. The radio frequency segment refers to the position close to the antenna in the radio frequency band, such as: the transceiver control unit can be located in the radio frequency segment; the analog intermediate frequency segment refers to the segment when the carrier signal is in an analog state, and the digital baseband segment refers to the baseband position. The combiner unit can be located in the analog intermediate frequency segment or in the digital baseband segment. Figure 4 As shown in FIG. 1 , the combining unit is located in the analog mid-frequency band.

[0100] The above description is about the communication process in which the first device 100 acts as a transmitter and the second device 200 acts as a receiver. Conversely, if the second device 200 acts as a transmitter and the first device 100 acts as a receiver, the above process can also be referred to, except that the sending process occurs in the second device 200 and the receiving process is sent in the first device 100.

[0101] In the embodiment of the present application, the transmission of carrier signals at different frequencies and different polarization directions to the antenna is achieved through the transceiver line, and the separation of the carrier signals at a certain polarization direction of at least two frequencies on each transceiver line is achieved through the combining unit, which can reduce the combining loss in the sending process and improve the signal gain in the receiving process.

[0102] The above dual-polarization scenario can also be found in Figure 5 The structure of the microwave device shown and the communication process are understood.

[0103] like Figure 5 As shown, the Figure 5 The microwave communication system and microwave device shown are similar to the above Figure 4 The schematic diagrams are basically the same, except that the combining unit is located in the digital baseband segment, such as: Figure 5The combiner unit 105, baseband 1031 and baseband 1041 are all located in the digital baseband segment. The combiner unit 108, baseband 1061 and baseband 1071 are all located in the digital baseband segment. When the combiner unit is located in the digital baseband segment, the difficulty of implementing the analog circuit can be reduced.

[0104] Taking into account that RF cables are not only costly but also cause insertion loss to signals, based on this, an embodiment of the present application also provides a microwave device and a microwave communication system of another structure, wherein the microwave device in the microwave communication system includes multiple antennas and multiple transceiver lines, and the multiple transceiver lines are included in at least two line groups, wherein each line group includes at least two transceiver lines, and at least two transceiver lines in different line groups share a combining unit; different transceiver lines in the same line group: are used to send carrier signals of the same frequency in different polarization directions, or, are used to receive carrier signals of at least two frequencies in different polarization directions.

[0105] Among them, at least two line groups include a third line group and a fourth line group, the third line group includes a third transceiver line and a fourth transceiver line, and the fourth line group includes a fifth transceiver line; a cross-polarization interference canceller is arranged between the baseband of the third transceiver line and the baseband of the fifth transceiver line; the antennas corresponding to the third transceiver line and the fourth transceiver line are configured with a polarization separator, the polarization separator is connected to the third transceiver line and the fourth transceiver line through a radio frequency cable, and the distance between the third transceiver line and the fourth transceiver line is less than a second threshold; the combining unit in the third line group is connected to the third The baseband of the transceiver line is connected to the baseband of the fourth transceiver line, and is connected to the receiving unit of the third transceiver line and the receiving unit of the fifth transceiver line through an intermediate frequency cable or a digital cable; the combining unit in the third line group is used to: separate the carrier signals of at least two frequencies in the same polarization direction received by the third transceiver line, and the carrier signals of at least two frequencies in the same polarization direction received by the fifth transceiver line, and the polarization direction of the carrier signals of at least two frequencies received by the third transceiver line is the same as the polarization direction of the carrier signals of at least two frequencies received by the fifth transceiver line.

[0106] In an embodiment of the present application, the distance between the third transceiver line and the fourth transceiver line is less than the second threshold value, which can reduce the use of RF cables. The receiving unit of the third transceiver line and the receiving unit of the fifth transceiver line are connected through an intermediate frequency cable or a digital cable, and carrier signals of different polarization directions of the same frequency point can be transmitted to the same antenna without the need for mutual transmission of RF cables, thereby reducing the use of RF cables and reducing the insertion loss caused by the use of longer RF cables.

[0107] In the embodiment of the present application, the second threshold is much smaller than the first threshold, for example, the first threshold may be 10 meters, and the second threshold may be 0.5 meters. Figure 4 and Figure 5 The microwave device shown has a structure that greatly reduces the amount of radio frequency cables used.

[0108] The microwave device and communication process in this case can be found in Figure 6 To understand.

[0109] like Figure 6 As shown, the structure of the microwave device can be referred to Figure 4 or Figure 5 The difference is that antenna 101 is connected to transceiver line 103 and transceiver line 104, and antenna 102 is connected to transceiver line 106 and transceiver line 107. Antenna 201 is connected to transceiver line 203 and transceiver line 204, and antenna 202 is connected to transceiver line 206 and transceiver line 207. The distance between transceiver lines in the same line group is short, so only a short RF cable is needed to connect to the corresponding transceiver line.

[0110] The combining unit 105 is shared by the transceiver line 103 and the transceiver line 106, and the combining unit 108 is shared by the transceiver line 104 and the transceiver line 107. The combining unit 205 is shared by the transceiver line 203 and the transceiver line 206, and the combining unit 208 is shared by the transceiver line 204 and the transceiver line 207. The combining unit and the transceiver line are connected via an intermediate frequency cable or a digital cable, and the cost of the intermediate frequency cable or the digital cable is much lower than that of the radio frequency cable.

[0111] Based on the above Figure 6 In the structure shown in FIG. 1 , in the dual-polarization scenario, the carrier signal transmission and reception process may be:

[0112] The baseband 1031 processes the carrier signal 301 of the first frequency point into a carrier signal 3011 of the first direction (e.g., horizontal), and the baseband 1041 processes the carrier signal 301 of the first frequency point into a carrier signal 3012 of the second direction (e.g., vertical). Then, the carrier signal 3011 of the first direction is transmitted in the transceiver line 103, and is transmitted to the polarization separator 1011 through a shorter RF cable, and the carrier signal 3012 of the second direction is transmitted in the transceiver line 104, and is transmitted to the polarization separator 1011 through a shorter RF cable. Then, the antenna 101 transmits the carrier signal 3011 of the first frequency point in the first direction and the carrier signal 3012 in the second direction.

[0113] Similarly, the baseband 1061 processes the carrier signal 302 of the second frequency point into a carrier signal 3021 in a first direction (e.g., horizontally), and the baseband 1071 processes the carrier signal 302 of the second frequency point into a carrier signal 3022 in a second direction (e.g., vertically). Then, the carrier signal 3021 in the first direction is transmitted in the transceiver line 106, and is transmitted to the polarization separator 1021 through a shorter RF cable, and the carrier signal 3022 in the second direction is transmitted in the transceiver line 107, and is transmitted to the polarization separator 1021 through a shorter RF cable. Then, the antenna 102 transmits the carrier signal 3021 of the second frequency point in the first direction and the carrier signal 3022 in the second direction.

[0114] Correspondingly, antenna 201 and antenna 202 of the second device will receive four carrier signals, namely: carrier signal 3011 of the first frequency in the first direction and carrier signal 3012 in the second direction, and carrier signal 3021 of the second frequency in the first direction and carrier signal 3022 in the second direction.

[0115] The polarization separator 2011 corresponding to the antenna 201 will transmit the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction to the transceiver line 203, and transmit the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction to the transceiver line 204.

[0116] The polarization separator 2021 corresponding to the antenna 202 will transmit the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction to the transceiver line 206, and transmit the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction to the transceiver line 207.

[0117] The combining unit 205 separates the carrier signal 3011 of the first frequency in the first direction and the carrier signal 3021 of the second frequency in the first direction on the transceiver line 203 and the transceiver line 206, and the baseband 2031 demodulates the carrier signal 3011 and the baseband 2041 demodulates the carrier signal 3021.

[0118] The combining unit 208 separates the carrier signal 3012 of the first frequency in the second direction and the carrier signal 3022 of the second frequency in the second direction on the transceiver line 204 and the transceiver line 207, and the baseband 2061 demodulates the carrier signal 3012 and the baseband 2071 demodulates the carrier signal 3022.

[0119] Above Figure 6The intermediate combiner unit is located in the digital baseband segment. In fact, the combiner unit may also be located in the analog intermediate frequency segment, which is not limited in this application.

[0120] The above description is about the communication process in which the first device 100 acts as a transmitter and the second device 200 acts as a receiver. Conversely, if the second device 200 acts as a transmitter and the first device 100 acts as a receiver, the above process can also be referred to, except that the sending process occurs in the second device 200 and the receiving process is sent in the first device 100.

[0121] In the embodiment of the present application, while reducing the combining loss in the sending process and improving the signal gain in the receiving process, the usage of RF cables can be reduced, and the insertion loss caused by using longer RF cables can be reduced.

[0122] In the implementation of the present application, the baseband, combining unit, RF transmitting unit, receiving unit and transceiver control unit in the above-mentioned transceiver line can be implemented by circuit or by software control. If implemented by software control, control parameters can be configured in the processor of the microwave device. During initialization, the processor can configure the functions of the baseband, combining unit, RF transmitting unit, receiving unit and transceiver control unit in the above-mentioned transceiver line according to the control parameters, thereby executing the functions performed by each unit in the above-mentioned embodiment.
