[Technical field]
[0001] This application is filed based on and claims priority to a Chinese patent application bearing application number 202011049878.6 and filing date September 29, 2020, the entire contents of which are hereby incorporated by reference into this application.

[0003] Antenna correction technology is one of the cores of beamforming technology and is a prerequisite for realizing the advantages of massive multiple input multiple output (MIMO) technology. In a frequency division duplexing (FDD) system, due to the operating characteristics of transmitting and receiving different frequencies, in the conventional method, the transmitting link cannot be used to transmit a correction sequence for the receiving frequency band, and the receiving link cannot be used to receive a correction sequence for the transmitting frequency band. Therefore, for signal correction of the receiving link, an additional transmitting module needs to be used to transmit a correction sequence that matches the receiving frequency band, and for signal correction of the transmitting link, an additional receiving module needs to be used to receive a correction sequence that matches the transmitting frequency band.
[0004] Therefore, the demand for additional transmit modules and additional receive modules requires the introduction of additional analog-to-digital conversion / digital-to-analog conversion (ADC / DAC) discrete devices, which in turn leads to problems such as increased layout area, increased cost, increased pin pressure of logic devices, and increased power supply configuration.

[0015] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be described in more detail below with reference to the drawings and examples, in which the specific examples described herein are only used to explain the present application and are not intended to limit the present application.
[0016] It should be noted that although a functional module division is shown in the schematic diagram of the device and a logical order is shown in the flowchart, the steps shown or described may, in some cases, be performed out of the order shown in the modular division of the device or the flowchart. The terms "first," "second," etc. in the specification, claims, or above drawings are not used to describe a particular order or priority, but are used to distinguish between similar objects.
[0017] The embodiments of the present application provide a communication device, a control method, a base station, and a computer-readable storage medium. The communication device includes a logic module, a transmission link, a reception link, an antenna module, a coupling module, and a correction conversion module. The transmission link is configured to transmit an RF signal of a first frequency bin. The reception link is configured to receive an RF signal of a second frequency bin. The antenna module is configured to transmit and receive the RF signal. The antenna module is respectively connected to the transmission link and the reception link. The coupling module is respectively connected to the transmission link, the reception link, and the antenna module. The correction conversion module is provided in the transmission link and / or the reception link. The logic module is respectively connected to the transmission link, the reception link, and the correction conversion module. The correction conversion module is provided in the transmitting link and / or the receiving link, so that when the correction conversion module is provided in the transmitting link, after controlling the correction conversion module, the transmitting link transmits the first correction signal of the second frequency bin, and the receiving link receives the first correction signal of the second frequency bin and transmits it to the logic module for correction of the RF signal. When the correction conversion module is provided in the receiving link, the transmitting link directly transmits the second correction signal of the first frequency bin, and controls the correction conversion module to enable the receiving link to receive the second correction signal of the first frequency bin and transmit it to the logic module for correction of the RF signal. That is, the RF signal is corrected by multiplexing the RF link. This eliminates the need to install additional transmitting modules, receiving modules, and ADC / DAC devices, and can avoid problems such as increased layout area, increased cost, increased pin pressure of logic devices, and increased power supply configuration.
[0018] Hereinafter, the embodiments of the present application will be further described with reference to the drawings. As shown in FIG. 1, FIG. 1 is a schematic diagram of a communication device in which an RF signal is corrected by multiplexing an RF link according to one embodiment of the present application.
[0019] As shown in Fig. 1, the communication device includes a logic module, a transmission link, a reception link, an antenna module, a coupling module, and a correction conversion module. The transmission link is configured to transmit an RF signal of a first frequency bin. The reception link is configured to receive an RF signal of a second frequency bin. The antenna module is configured to transmit and receive the RF signal. The antenna module is connected to the transmission link and the reception link, respectively. The coupling module is connected to the transmission link, the reception link, and the antenna module, respectively. The logic module is connected to the transmission link, the reception link, and the correction conversion module, respectively. The correction conversion module is provided in the transmission link and / or the reception link. In Fig. 1, the correction conversion module is not shown.
[0020] When the correction conversion module is provided in the transmission link, the logic module is configured to transmit a first correction signal to the transmission link and operate the correction conversion module to cause the first correction signal to be modulated to a second frequency bin by the transmission link and the first correction signal to be forwarded to the antenna module by the coupling module. The logic module obtains the first correction signal of the second frequency bin received by the reception link from the antenna module to perform correction of the RF signal, thereby performing uplink antenna correction.
[0021] When the correction conversion module is provided in the receiving link, the logic module transmits a second correction signal to the transmitting link, causes the second correction signal to be modulated to the first frequency bin by the transmitting link, and transmits the second correction signal to the combining module by the antenna module, and controls the correction conversion module to modulate the second correction signal of the first frequency bin received by the receiving link from the combining module. The logic module obtains the second correction signal received by the receiving link to perform correction of the RF signal, thereby performing downlink antenna correction.
[0022] In one embodiment, as shown in FIG. 2, the transmission link includes a digital-to-analog conversion module, an up-conversion module, and a first changeover switch. The correction conversion module is provided in the transmission link. The correction conversion module and the up-conversion module are connected to form a first conversion unit. Specifically, the logic module, the digital-to-analog conversion module, the first conversion unit, the first changeover switch, and the antenna module are connected in sequence. The first changeover switch is further connected to the combination module and the logic module. The logic module is specifically configured to send a first correction signal to the transmission link, operate and control the correction conversion module so that the first correction signal is modulated to a second frequency bin by the transmission link, control the first changeover switch to make the first conversion unit and the combination module conductive, and transmit the first correction signal to the antenna module by the first changeover switch and the combination module, and obtain the first correction signal of the second frequency bin received by the reception link from the antenna module to correct the RF signal.
[0023] In this embodiment, the transmission link is provided with a correction conversion module, so that the multiplexing of the transmission link can be realized. Specifically, when the communication device needs to transmit communication service data to the outside, the communication service data signal is transmitted from the logic module to the transmission link. In this case, the correction conversion module is bypassed. The communication service data signal is modulated to a first frequency bin by the digital-to-analog conversion module and the up-conversion module of the transmission link, and then transmitted through the antenna module. When the RF signal needs to be corrected, the first correction signal is transmitted from the logic module to the transmission link, and is modulated to a second frequency bin by the digital-to-analog conversion module, the correction conversion module, and the up-conversion module, and then passes through the first switch, the coupling module, and the antenna module in sequence to the receiving link. The receiving link modulates the received first correction signal of the second frequency bin and transmits it to the logic module for RF signal correction. Thus, uplink antenna correction is performed.
[0024] Here, the correction conversion module used in this embodiment is provided at the rear end of the digital-to-analog conversion module, and therefore converts analog signals, and may be implemented as an analog mixer.
[0025] In addition, the positional relationship between the correction conversion module and the up-conversion module in the first conversion unit shown in FIG. 2 can be interchanged. When both of these are actually used, they can be implemented as the same device, but the degree of conversion for the analog signal is different. Note that the correction conversion module and the up-conversion module constitute the first conversion unit, but it is not required that the correction conversion module and the up-conversion module be integrated into the same device. The correction conversion module and the up-conversion module may be two independent modules, or may be integrated into another device. For example, the up-conversion module may be integrated into the same device together with the digital-to-analog conversion module.
[0026] However, an amplification module may be provided between the first changeover switch and the antenna module so that a signal to be transmitted via the antenna module is amplified before being transmitted to the outside.
[0027] In one embodiment, as shown in FIG. 3, the transmission link includes a digital-to-analog conversion module, an up-conversion module, and a first switch. The correction conversion module is provided in the transmission link. The correction conversion module and the up-conversion module are connected to form a first conversion unit. Specifically, the logic module, the first conversion unit, the digital-to-analog conversion module, the first switch, and the antenna module are sequentially connected. The first switch is further connected to the combination module and the logic module. The logic module is specifically configured to send a first correction signal to the transmission link, operate and control the correction conversion module to make the first correction signal modulated to a second frequency bin by the transmission link, control the first switch to make the digital-to-analog conversion module and the combination module conductive, and transmit the first correction signal to the antenna module by the first switch and the combination module, and obtain the first correction signal of the second frequency bin received by the reception link from the antenna module to perform correction of the RF signal.
[0028] In this embodiment, compared with the embodiment shown in FIG. 2, the correction conversion module is provided at the end of the digital-to-analog conversion module to convert a digital signal, and is different in that it can be implemented as a digital mixer, for example, a numerically controlled oscillator (NCO). Similarly, the front-to-back positional relationship of the correction conversion module and the up-conversion module in the first conversion unit shown in FIG. 3 can be interchanged. Although the correction conversion module and the up-conversion module constitute the first conversion unit, it is not required that the correction conversion module and the up-conversion module are integrated into the same device. The correction conversion module and the up-conversion module may be two independent modules, or may be integrated into another device. For example, the up-conversion module may be integrated into the same device together with the digital-to-analog conversion module. The remaining working principle of the communication device of this embodiment is the same as that of FIG. 2, and will not be described in detail here.
[0029] In one embodiment, as shown in FIG. 4, the receiving link includes a second changeover switch, a down-conversion module, and an analog-to-digital conversion module. The correction conversion module is provided in the receiving link. The correction conversion module and the down-conversion module are connected to form a second conversion unit. Specifically, the antenna module, the second changeover switch, the second conversion unit, the analog-to-digital conversion module, and the logic module are connected in sequence. The second changeover switch is further connected to the combining module and the logic module. The logic module is specifically configured to send a second correction signal to the transmitting link, modulate the second correction signal to a first frequency bin, and transmit the second correction signal to the combining module by the antenna module, control the second changeover switch to make the combining module and the second conversion unit conductive, cause the receiving link to receive the second correction signal of the first frequency bin from the combining module by the second changeover switch, and operate and control the correction conversion module to modulate the second correction signal of the first frequency bin received by the receiving link and transmit it to the logic module, and obtain the second correction signal received by the receiving link to perform correction of the RF signal.
[0030] In this embodiment, the receiving link is provided with a correction conversion module, so that the multiplexing of the receiving link can be realized. Specifically, when the communication device receives communication service data transmitted from the outside, the antenna module transmits the received communication service data signal of the first frequency bin to the transmitting link. In this case, the correction conversion module is bypassed. The communication service data signal of the first frequency bin is modulated by the down-conversion module and the analog-to-digital conversion module of the receiving link, and then transmitted to the logic module. When the RF signal needs to be corrected, the second correction signal is transmitted from the logic module to the transmitting link, and is modulated to the first frequency bin by the transmitting link, and then passes through the antenna module, the coupling module, and the second changeover switch in sequence to reach the receiving link. At this time, the correction conversion module is operated and controlled, and then the second correction signal is modulated by the correction conversion module, the down-conversion module, and the analog-to-digital conversion module, and then transmitted to the logic module for RF signal correction. In this way, the downlink antenna correction is performed.
[0031] Here, the correction conversion module used in this embodiment is provided at the tip of the analog-to-digital conversion module, and therefore converts analog signals, and may be implemented as an analog mixer.
[0032] In addition, the positional relationship between the correction conversion module and the down-conversion module in the second conversion unit shown in FIG. 4 can be interchanged. When both of these are actually used, they can be implemented as the same device, but the degree of conversion for the analog signal is different. Note that the correction conversion module and the down-conversion module constitute the second conversion unit, but it is not required that the correction conversion module and the down-conversion module be integrated into the same device. The correction conversion module and the down-conversion module may be two independent modules, or may be integrated into another device. For example, the down-conversion module may be integrated into the same device together with the analog-to-digital conversion module.
[0033] However, an amplification module may be provided between the antenna module and the second changeover switch, so that the signal received by the antenna module is amplified before being transmitted to the receiving link.
[0034] In one embodiment, as shown in FIG. 5, the receiving link includes a second changeover switch, a down-conversion module, and an analog-to-digital conversion module. The correction conversion module is provided in the receiving link. The correction conversion module and the down-conversion module are connected to form a second conversion unit. Specifically, the antenna module, the second changeover switch, the analog-to-digital conversion module, the second conversion unit, and the logic module are sequentially connected. The second changeover switch is further connected to the combining module and the logic module. The logic module is specifically configured to send a second correction signal to the transmitting link, modulate the second correction signal to a first frequency bin, and transmit the second correction signal to the combining module by the antenna module, control the second changeover switch to make the combining module and the down-conversion module conductive, and cause the receiving link to receive the second correction signal of the first frequency bin from the combining module by the second changeover switch, and operate and control the correction conversion module to modulate the second correction signal of the first frequency bin received by the receiving link and transmit it to the logic module, and obtain the second correction signal received by the receiving link to perform correction of the RF signal.
[0035] In this embodiment, compared with the embodiment shown in FIG. 4, the difference is that the correction conversion module is provided at the rear end of the analog-to-digital conversion module, so that it converts digital signals and can be implemented as a digital mixer, for example, a numerically controlled oscillator (NCO). Similarly, the front-to-back positional relationship of the correction conversion module and the down-conversion module in the second conversion unit shown in FIG. 5 can be interchanged. Although the correction conversion module and the down-conversion module constitute the second conversion unit, it is not required that the correction conversion module and the down-conversion module are integrated into the same device. The correction conversion module and the down-conversion module may be two independent modules, or may be integrated into another device. For example, the down-conversion module may be integrated into the same device together with the analog-to-digital conversion module. The remaining working principle of the communication device of this embodiment is the same as that of FIG. 4, so it will not be described in detail here.
[0036] In one embodiment, as shown in FIG. 6, the communication device includes a logic module, a transmitting link, a receiving link, an antenna module, a combining module, a first correction conversion module, a second correction conversion module, and a third changeover switch.
[0037] The transmission link includes a digital-to-analog conversion module, an up-conversion module, and a first changeover switch. The first correction conversion module is provided in the transmission link. The first correction conversion module and the up-conversion module are connected to form a first conversion unit. The logic module, the digital-to-analog conversion module, the first conversion unit, the first changeover switch, and the antenna module are connected in sequence.
[0038] The receiving link includes a second switch, a down-conversion module, and an analog-to-digital conversion module. The second correction conversion module is provided in the receiving link. The second correction conversion module and the down-conversion module are connected to form a second conversion unit. The antenna module, the second switch, the second conversion unit, the analog-to-digital conversion module, and the logic module are connected in sequence.
[0039] The third switch is respectively connected to the first switch, the second switch and the combination module. The first correction conversion module, the second correction module, the first switch, the second switch and the third switch are all connected to the logic module.
[0040] Specifically, the logic module is The antenna module is configured to transmit a first correction signal to the transmitting link, operate and control the first correction conversion module so that the first correction signal is modulated to a second frequency bin by the transmitting link, control the first switch to make the first conversion unit and the third switch conductive, and control the third switch to make the first switch and the coupling module conductive, so that the first correction signal is transmitted to the antenna module by the first switch, the third switch and the coupling module, and the receiving link obtains the first correction signal of the second frequency bin received from the antenna module to perform correction of the RF signal; The antenna module is configured to transmit a second correction signal to a transmitting link, modulating the second correction signal to a first frequency bin, controlling a first selector switch to bring the first conversion unit and the antenna module into conduction, transmitting the second correction signal to the combining module by the first selector switch and the antenna module, controlling a third selector switch to bring the combining module and the second selector switch into conduction, and controlling the second selector switch to bring the third selector switch and the second conversion unit into conduction, causing a receiving link to receive the second correction signal of the first frequency bin from the combining module via the second selector switch and the third selector switch, operating and controlling the second correction conversion module to modulate the second correction signal of the first frequency bin received by the receiving link and transmit it to the logic module, and obtaining the second correction signal received by the receiving link to correct the RF signal.
[0041] Here, the first correction conversion module used in this embodiment is provided at the rear end of the digital-to-analog conversion module, so that it converts analog signals and can be implemented as an analog mixer.The second correction conversion module used in this embodiment is provided at the front end of the analog-to-digital conversion module, so that it converts analog signals and can be implemented as an analog mixer.
[0042] In addition, the front-back positional relationship of the first correction conversion module and the up-conversion module in the first conversion unit shown in FIG. 6 can be interchanged. The first correction conversion module and the up-conversion module constitute the first conversion unit, but it is not required that the first correction conversion module and the up-conversion module are integrated into the same device. The correction conversion first module and the up-conversion module may be two independent modules, or may be integrated into another device. For example, the up-conversion module may be integrated into the same device together with the digital-to-analog conversion module. Similarly, the front-back positional relationship of the second correction conversion module and the down-conversion module in the second conversion unit can be interchanged. The second correction conversion module and the down-conversion module constitute the second conversion unit, but it is not required that the second correction conversion module and the down-conversion module are integrated into the same device. The second correction conversion module and the down-conversion module may be two independent modules, or may be integrated into another device. For example, the down-conversion module may be integrated into the same device together with the analog-to-digital conversion module.
[0043] However, the first conversion unit may also be provided at the front end of the digital-to-analog conversion module. In such a case, the first correction conversion module in the first conversion unit converts digital signals and may be implemented as a digital mixer, for example, a numerically controlled oscillator (NCO). Similarly, the second conversion unit may also be provided at the rear end of the analog-to-digital conversion module. In such a case, the second correction conversion module in the second conversion unit converts digital signals and may be implemented as a digital mixer, for example, a numerically controlled oscillator (NCO).
[0044] However, an amplifier module may be provided between the first switch and the antenna module, so as to amplify the signal to be transmitted by the antenna module before transmitting it to the outside. Similarly, an amplifier module may be provided between the antenna module and the second switch, so as to amplify the signal received by the antenna module before transmitting it to the receiving link.
[0045] Based on the structures of the communication devices of the above embodiments, various embodiments of the control method for the communication device will be described below.
[0046] As shown in FIG. 7, FIG. 7 is a flow chart of a control method of a communication device according to an embodiment of the present application. The control method can be applied to the communication device of the embodiment shown in FIG. 1. In the figure, the correction conversion module is not shown, and the correction conversion module is provided in the transmission link. The control method includes, but is not limited to, steps S710 to S730.
[0047] Step S710: Send a first correction signal to the transmission link. Step S720: Activate the correction conversion module so that the first correction signal is modulated to a second frequency bin by the transmission link, and the first correction signal is forwarded to the antenna module by the combination module.
[0048] Step S730: Obtain a first correction signal received from the antenna module through the receive link and modulated to a second frequency bin to perform correction of the RF signal.
[0049] In this embodiment, when the RF signal needs to be corrected, the first correction signal is transmitted from the logic module to the transmit link, and the correction conversion module is operated to cause the first correction signal to be modulated to the second frequency bin by the transmit link. The first correction signal then passes through the coupling module and the antenna module to the receive link. The receive link modulates the received first correction signal to the second frequency bin and transmits it to the logic module for RF signal correction, thereby achieving uplink antenna correction.
[0050] As shown in Fig. 8, Fig. 8 is a flow chart of a control method of a communication device according to another embodiment of the present application. The control method can be applied to the communication device in the embodiment shown in Fig. 1.

[0053] Step S830: Obtain a second correction signal received by the receiving link, and perform correction of the RF signal.
[0054] In this embodiment, when the RF signal needs to be corrected, the second correction signal is transmitted from the logic module to the transmit link, and is modulated by the transmit link to the first frequency bin, and then passes through the antenna module and the coupling module to the receive link, thereby controlling the operation of the correction conversion module. Then, the second correction signal is modulated by the receive link, and then transmitted to the logic module for correction of the RF signal, thereby achieving downlink antenna correction.
[0055] As shown in Fig. 9, Fig. 9 is a flowchart of a control method for a communication device according to another embodiment of the present application. The control method can be applied to the communication device in the embodiment shown in Fig. 2. The control method includes, but is not limited to, steps S910 to S940.
[0056] Step S910: Send a first correction signal from the digital-to-analog conversion module to a transmission link.
[0057] Step S920: Activate a correction conversion module so that the first correction signal is modulated to a second frequency bin by the transmission link.
[0058] Step S930: Control the first changeover switch to make the first conversion unit and the combining module conductive, so that the first correction signal is transmitted to the antenna module by the first changeover switch and the combining module.
[0059] Step 940: Obtain a first correction signal of a second frequency bin received by the receive link from the antenna module to correct the RF signal.
[0060] In this embodiment, when the RF signal needs to be corrected, the first correction signal is transmitted from the logic module to the transmission link, and is modulated to the second frequency bin by the digital-to-analog conversion module, the up-conversion module and the correction conversion module, and then passes through the first switch, the combining module and the antenna module to the reception link. The reception link modulates the received first correction signal of the second frequency bin and transmits it to the logic module for RF signal correction, thereby achieving uplink antenna correction.
[0061] 3 is substantially the same as that in the present embodiment, but has two differences: in step S910, the first correction signal is sent from the first conversion unit to the transmission link, rather than from the digital-to-analog conversion module to the transmission link; in step S930, the first selector switch is controlled to make the digital-to-analog conversion and the combination module conductive, rather than making the first conversion unit and the combination module conductive;
[0062] As shown in Fig. 10, Fig. 10 is a flowchart of a control method for a communication device according to another embodiment of the present application. The control method is applicable to the communication device in the embodiment shown in Fig. 4. The control method includes, but is not limited to, steps S1010 to S1040.
[0063] Step S1010: Send a second correction signal to a transmission link, such that the second correction signal is modulated to a first frequency bin, and the second correction signal is transmitted by the antenna module to the combining module.
[0064] Step S1020: Control the second changeover switch to make the combining module and the second conversion unit conductive, so that the receiving link receives the second correction signal of the first frequency bin from the combining module through the second changeover switch.

[0066] Step S1040: Obtain the second correction signal received by the receiving link from the analog-to-digital conversion module, and perform correction of the RF signal.
[0067] In this embodiment, when the RF signal needs to be corrected, the second correction signal is transmitted from the logic module to the transmission link, and is modulated to the first frequency bin by the transmission link, and then passes through the antenna module, the coupling module, and the second switch to the reception link, and controls the operation of the correction conversion module. Then, the second correction signal is modulated by the correction conversion module, the down-conversion module, and the analog-to-digital conversion module, and then transmitted to the logic module for RF signal correction, thereby performing downlink antenna correction.
[0068] 5 is substantially the same as that of the present embodiment, but has two differences: in step S1020, the second selector switch is controlled to connect the combination module and the analog-to-digital conversion module, rather than connecting the combination module and the second conversion unit; in step S1040, the second correction signal is obtained from the second conversion unit, rather than obtaining the second correction signal from the analog-to-digital conversion module;
[0069] As shown in Fig. 11, Fig. 11 is a flowchart of a control method for a communication device according to another embodiment of the present application. The control method is applicable to the communication device in the embodiment shown in Fig. 6. The control method includes, but is not limited to, steps S1110 to S1140.

[0071] Step S1130: Control the first switch to make the first conversion unit and the third switch conductive, and control the third switch to make the first switch and the combination module conductive, so that the first correction signal is transmitted to the antenna module by the first switch, the third switch and the combination module.
[0072] Step S1140: Obtain a first correction signal of a second frequency bin received by the receiving link from the antenna module, and perform correction of the RF signal.
[0073] This embodiment is similar to the control method of FIG. 9, except that the control of the third changeover switch is added, and the remaining functions and actions are all the same, so they will not be described in detail here.
[0074] In addition, when the first conversion unit in FIG. 6 is provided at the end of the digital-to-analog conversion module, in step S1130, the first changeover switch is controlled to bring the digital-to-analog conversion module and the third changeover switch into conduction, rather than bringing the first conversion unit and the third changeover switch into conduction.
[0075] As shown in Fig. 12, Fig. 12 is a flowchart of a control method for a communication device according to another embodiment of the present application. The control method is applicable to the communication device in the embodiment shown in Fig. 6. The control method includes, but is not limited to, steps S1210 to S1250.
[0076] Step S1210: Send a second correction signal to a transmission link, such that the second correction signal is modulated to a first frequency bin.
[0077] Step S1220: Control the first changeover switch to make the first conversion unit and the antenna module conductive, so that the second correction signal is transmitted to the combination module by the first changeover switch and the antenna module.
[0078] Step S1230: Control the third switch to make the combination module and the second switch conductive, and control the second switch to make the third switch and the second conversion unit conductive, so that the receiving link receives the second correction signal of the first frequency bin from the combination module through the second switch and the third switch.
[0079] Step S1240: Operate and control a second correction conversion module to modulate the second correction signal of the first frequency bin received by the receiving link and transmit it to the logic module.
[0080] Step S1250: Obtain a second correction signal received by the receiving link, and perform correction of the RF signal.
[0081] This embodiment is similar to the control method of FIG. 10, except that the control of the third switch is added, and the remaining functions and actions are all the same, so they will not be described in detail here.
[0082] 6 is provided at the front end of the digital-to-analog conversion module, the first changeover switch is controlled in step S1220 to provide electrical continuity between the digital-to-analog conversion module and the antenna module, rather than between the first conversion unit and the antenna module. When the second conversion unit is provided at the rear end of the analog-to-digital conversion module, the second changeover switch is controlled in step S1230 to provide electrical continuity between the third changeover switch and the analog-to-digital conversion module, rather than between the third changeover switch and the second conversion unit.
[0083] An example of a hardware circuit embodiment of the communication device of the above embodiment of the present application is shown in Fig. 13. Based on the hardware circuit in Fig. 13, the procedure for correcting the RF signal is specifically as follows.
[0084] As an example, the frequency band range in which the transmission link of a communication device normally operates is 1805 MHz to 1880 MHz, and the frequency band range in which the reception link normally operates is 1710 MHz to 1785 MHz.
[0085] 1. In uplink correction, the first correction signal is transmitted from the logic module to the multiplexed transmission link by the two-speed motor integrated protector (JESD). At this time, the frequency of the digital signal to the numerically controlled oscillator (NCO) is 0MHz, the NCO function is turned on, and the frequency carrier capability of the NCO is (1785+1710) / 2-(1880+1805) / 2=-95MHz. After passing through the NCO, the intermediate frequency signal becomes -95MHz. After passing through the DAC, after being upconverted by the external high-speed LO upconversion module, the LO=(1880+1805) / 2=1842.5MHz is output, and the frequency of the analog signal is 1747.5MHz, which is equal to the center frequency of the uplink. At this time, the switch sw1 in the transmission link makes the transmission link and the coupling module conductive, and the first correction signal is distributed to each receiving channel by the coupling module.
[0086] 2. In downlink correction, the second correction signal is sent from the logic module to the normal transmission link by the two-speed motor integrated protector (JESD). At this time, the NCO in the transmission link is in a bypass state, and the signal output after upconversion by the transmission link is a 1842.5MHz signal. The second correction signal goes from the antenna module to the combining module, and is finally combined, passes through the switch sw3 and the switch sw2, and then goes to the receiving link. After passing through the ADC device, the intermediate frequency signal becomes 95MHz, and then passes through the NCO, and the intermediate frequency signal becomes 0MHz, and is sent to the JESD.
[0087] Another specific embodiment of the hardware circuit of the communication device of the above embodiment of the present application is shown in Figure 14. Compared with the embodiment shown in Figure 13, this embodiment is different in that instead of adopting the NCO module, the up-down assisted conversion is simulated by an external high-speed LO up-down conversion module. The details are as follows:
[0088] 1. In uplink correction, the logic module sends a 0MHz digital signal, which is upconverted by the DAC itself, and then a (1880+1805) / 2=1842.5MHz analog signal is output, which is downconverted to -95MHz by the auxiliary LO, and a 1747.5MHz first correction signal is output.
[0089] 2. In downlink correction, the second correction signal is transmitted from the logic module to the normal transmit link by the two-speed motor integrated protector (JESD). At this time, the NCO in the transmit link is in a bypass state, and the signal output after upconversion by the transmit link is a 1842.5MHz signal. The second correction signal is finally combined after reaching the combining module from the antenna module, and passes through the switch sw3 and the switch sw2 to reach the receive link. After being downconverted to -95MHz by the auxiliary LO, a second correction signal of 1747.5MHz is obtained, which is then received by the ADC working in the uplink frequency band.
