Description

Technical Field

[0001] This invention relates to the field of co-channel interference processing technology, specifically to a system, method, device, and storage medium for processing co-channel interference in image and data transmission modules. Background Technology

[0002] In drone systems, multiple image transmission modules are typically configured on the ground to receive data and information collected by multiple drones. When multiple image transmission modules work simultaneously, noise crosstalk occurs due to the same operating frequency band of the radio frequency modules, causing problems such as data loss and increased bit error rate. The interference is particularly noticeable during takeoff and landing, which can lead to problems such as drones being unable to land or take off.

[0003] Among related technologies, co-channel interference handling methods include frequency band isolation, spatial isolation, and point-to-multipoint processing. Frequency band isolation uses frequency hopping technology to allow different drones to switch between different frequency bands for image transmission, avoiding continuous co-channel transmission. However, when there are many drones, it is impossible to completely avoid all frequency bands. Spatial isolation increases the spatial distance between ground terminals to reduce signal strength, but spatial isolation is costly. Point-to-multipoint processing involves one ground terminal corresponding to multiple drones. Due to data bandwidth limitations, it is impossible to transmit multiple high-definition videos or large amounts of data simultaneously. Summary of the Invention

[0004] This invention provides a system, method, device, and storage medium for handling co-channel interference in image and data transmission modules, in order to solve the problem of data bandwidth limitation caused by co-channel interference handling methods in related technologies.

[0005] In a first aspect, the present invention provides a system for handling co-channel interference in a data transmission module, comprising: multiple data transmission modules and a signal control processing module; each data transmission module includes a data transmission unit, a radio frequency switch, a first channel, a second channel, a signal processing unit, and an antenna unit; the output terminal of the data transmission unit is connected to the input terminal of the radio frequency switch, the output terminal of the radio frequency switch is connected to the input terminals of the first channel and the second channel respectively, the output terminal of the first channel is connected to the antenna unit, and the output terminal of the second channel is connected to the antenna unit through the signal processing unit; the signal control processing module is used to determine the operating state of the data transmission unit based on the radio frequency performance indicators fed back by the data transmission unit, and to control the radio frequency switch to turn on the second channel if the operating state of the data transmission unit is abnormal; the signal processing unit is used to perform anti-interference processing on the radio frequency signal transmitted through the second channel, so that the antenna unit can communicate with the UAV based on the anti-interference processed radio frequency signal.

[0006] The image-data transmission module co-channel interference processing system of the present invention includes: multiple data transmission modules and a signal control and processing module. Each data transmission module corresponds to a UAV, realizing data transmission between multiple UAVs and the data transmission module. Each data transmission module of the present invention includes an image-data transmission unit, a radio frequency switch, a first channel, a second channel, a signal processing unit, and an antenna unit. The constituent units of the data transmission module are clearly defined, and the functional positioning of each unit within the module is clarified. The output end of the image-data transmission unit is connected to the input end of the radio frequency switch. The output end of the radio frequency switch is connected to the input ends of the first channel and the second channel, respectively. The output end of the first channel is connected to the antenna unit, and the output end of the second channel is connected to the antenna unit through the signal processing unit. The signal connection paths of each unit within the data transmission module are clearly defined, providing hardware connection guarantees for signal transmission and processing within the module, forming a complete image-data transmission module co-channel interference processing system. The signal control processing module of this invention is used to determine the operating status of the image and data transmission unit based on the radio frequency performance indicators fed back by the image and data transmission unit, and to control the frequency switch to turn on the second channel if the operating status of the image and data transmission unit is abnormal. Through the control of the signal control processing module, the switching between the first and second channels is achieved by intelligently judging and controlling the frequency switch. The signal processing unit of this invention is used to perform anti-interference processing on the radio frequency signal transmitted through the second channel, so that the antenna unit can communicate with the UAV based on the anti-interference processed radio frequency signal. When switching to the second channel, it indicates that the operating status of the image and data transmission unit is abnormal, and there may be co-channel interference. Therefore, anti-interference processing is performed on the radio frequency signal transmitted through the second channel to ensure that the radio frequency signal for communication between the antenna unit and the UAV is not affected by co-channel interference. Compared with related technologies, this invention achieves independent control of multiple UAVs by judging and performing anti-interference processing for co-channel interference, solving the problem of data transmission errors caused by co-channel interference. It eliminates the need for frequency band switching, meets anti-interference processing requirements under all abnormal conditions, eliminates the need for spatial isolation, reduces the cost of anti-interference processing, and can simultaneously transmit multiple channels of high-definition video or large amounts of data, ensuring stable data transmission between the UAV and the ground terminal.

[0007] In one optional implementation, the signal control processing module is further configured to control the RF switch to turn on the first channel based on the normal operating state of the image data transmission unit.

[0008] In one optional implementation, the radio frequency performance indicators include the drone's receive and transmit power indicators; the signal control processing module includes a first judgment unit; the first judgment unit is used to compare the drone's receive and transmit power indicators fed back by the drone receiver with a preset drone receive and transmit power threshold, and if the drone's receive and transmit power indicators are less than the preset drone receive and transmit power threshold, it is determined that the working state of the image and data transmission unit is abnormal, and if the drone's receive and transmit power indicators are greater than or equal to the preset drone receive and transmit power threshold, it is determined that the working state of the image and data transmission unit is normal.

[0009] In one optional implementation, the signal processing unit includes a signal amplification subunit; the signal amplification subunit is used to amplify the transmission power of the radio frequency signal transmitted through the second channel based on a power amplifier, since the received transmission power index of the UAV is less than a preset received transmission power threshold of the UAV.

[0010] The fact that the drone's received transmission power index is less than the preset drone received transmission power threshold indicates that the received transmission power is too low due to co-channel interference, which will lead to unstable data transmission. The present invention uses a power amplifier to amplify the transmission power of the radio frequency signal transmitted through the second channel, ensuring the signal strength when the antenna unit communicates with the drone, avoiding communication quality degradation or interruption due to insufficient transmission power, and effectively improving the communication stability and reliability of the drone in complex interference environments.

[0011] In one optional implementation, the radio frequency performance indicators include the ground-end received transmit power indicator; the signal control processing module includes a second judgment unit; the second judgment unit is used to compare the ground-end received transmit power indicator fed back by the map data transmission unit with a preset ground-end received transmit power threshold, and if the ground-end received transmit power indicator is less than the preset ground-end received transmit power threshold, it determines that the working state of the map data transmission unit is abnormal, and if the ground-end received transmit power indicator is greater than or equal to the preset ground-end received transmit power threshold, it determines that the working state of the map data transmission unit is normal.

[0012] In one optional implementation, the signal processing unit includes a noise reduction processing subunit; the noise reduction processing subunit is used to perform signal amplification and noise suppression processing on the radio frequency signal transmitted through the second channel based on a low-noise amplifier, according to the ground end receiving transmit power index being less than a preset ground end receiving transmit power threshold.

[0013] The ground-end received transmit power index of this invention is less than the preset ground-end received transmit power threshold, indicating that the received transmit power is too low due to excessive noise, affecting the stability of data transmission. Based on the low-noise amplifier, the radio frequency signal transmitted through the second channel is amplified and noise suppressed, effectively filtering noise interference, increasing the strength of the received transmit power at the ground end, and improving the purity of the signal. This ensures the signal quality when the antenna unit communicates with the UAV, avoids communication errors and disconnection caused by insufficient receiving sensitivity, and significantly enhances the anti-interference capability and communication stability of the image and data transmission module in complex interference scenarios.

[0014] Secondly, the present invention provides a method for handling co-channel interference of a map data transmission module, comprising: determining the working state of the map data transmission unit based on the radio frequency performance indicators fed back by the map data transmission unit, and controlling the radio frequency switch to turn on the second channel if the working state of the map data transmission unit is abnormal; and performing anti-interference processing on the radio frequency signal transmitted through the second channel so that the antenna unit can communicate with the UAV based on the anti-interference processed radio frequency signal.

[0015] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the co-channel interference processing method of the image and data transmission module described in the second aspect.

[0016] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to execute the method for handling co-channel interference of the image and data transmission module described in the second aspect above.

[0017] Fifthly, the present invention provides a computer program product, including computer instructions, which are used to cause the computer to execute the method for handling co-channel interference of the image and data transmission module described in the second aspect above.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] As an optional application scenario of this invention, such as Figure 1 As shown, this is a system for handling co-channel interference between multiple drones and the image and data transmission module according to an embodiment of the present invention. Figure 1The system includes three drones. In this embodiment of the invention, various co-channel interference scenarios exist. For example, co-channel interference may occur when a drone passively returns to home or actively returns to home. When a drone passively returns to home, the drone hangar (nest, landing platform) server can obtain the drone's coordinate information in real time through the image and data transmission module. By comparing the coordinate differences between the drone and the drone hangar, it can determine whether the drone has entered the landing state. When the latitude and longitude coincide or are close to coinciding, co-channel interference may occur. When a drone actively returns to home, the drone hangar (nest, landing platform) server can determine which image and data transmission unit is working while issuing the drone return command through the image and data transmission module. When co-channel interference occurs at this time, it can be handled by the co-channel interference processing system of the image and data transmission module according to this embodiment of the invention.

[0024] This invention provides a system for handling co-channel interference in a data transmission module. By setting up two channels and switching between them when co-channel interference processing is required, the system achieves the effect of anti-interference processing of radio frequency signals.

[0025] According to an embodiment of the present invention, a processing system embodiment for co-channel interference of a data transmission module is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0026] This embodiment provides a system for handling co-channel interference in image and data transmission modules. Figure 2 This is a schematic diagram of a first structural embodiment of a data transmission module co-channel interference processing system according to an embodiment of the present invention, as shown below. Figure 2As shown, the system includes: multiple data transmission modules 20 and a signal control and processing module 21; each data transmission module 20 includes an image-to-data transmission unit 201, a frequency-to-radio switch 202, a first channel 203, a second channel 204, a signal processing unit 205, and an antenna unit 206; the output terminal of the image-to-data transmission unit 201 is connected to the input terminal of the frequency-to-radio switch 202, the output terminal of the frequency-to-radio switch 202 is connected to the input terminals of the first channel 203 and the second channel 204 respectively, the output terminal of the first channel 203 is connected to the antenna unit 206, and the second channel 204 is connected to the antenna unit 206. The output of 204 is connected to the antenna unit 206 via the signal processing unit 205; the signal control processing module 21 is used to determine the working status of the image data transmission unit 201 based on the radio frequency performance indicators fed back by the image data transmission unit 201, and to control the radio frequency switch 202 to turn on the second channel 204 if the working status of the image data transmission unit 201 is abnormal; the signal processing unit 205 is used to perform anti-interference processing on the radio frequency signal transmitted through the second channel 204 so that the antenna unit 206 can communicate with the UAV based on the anti-interference processed radio frequency signal.

[0027] In some optional implementations, the signal control processing module 21 is also used to control the frequency switch 202 to turn on the first channel 203 according to the normal working state of the image data transmission unit 201.

[0028] In some alternative implementations, the number of data transmission modules 20 can be configured according to the number of drones, with one drone corresponding to one data transmission module 20. For example, Figure 2 It includes two data transmission modules 20.

[0029] In some optional implementations, each data transmission module 20 includes a data transmission unit 201, a radio frequency switch 202 corresponding to the data transmission unit 201, used to switch communication paths; a signal processing unit 205, used for signal amplification and fixing the communication channel; and an antenna unit 206 used for signal transmission and reception.

[0030] In some alternative implementations, the radio frequency switch 202 can be a double-pole double-throw switch. Under the control of the signal control processing module 21, when the working state of the image and data transmission unit 201 is abnormal, the radio frequency switch 202 connects the second channel 204, and when the working state of the image and data transmission unit 201 is normal, the radio frequency switch 202 connects the first channel 203.

[0031] In some optional implementations, when multiple image and data transmission units 201 are in an abnormal operating state, the data transmission module 20 with the most severe co-channel interference is selected for priority processing. For example, when multiple image and data transmission units 201 are in an abnormal operating state, the data transmission module 20 corresponding to the UAV closest to the ground is selected for priority processing.

[0032] The image-data transmission module co-channel interference processing system provided in this embodiment includes: multiple data transmission modules 20 and a signal control and processing module 21. Each data transmission module 20 corresponds to a UAV, realizing data transmission between multiple UAVs and the data transmission module 20. Each data transmission module 20 in this embodiment includes an image-data transmission unit 201, a radio frequency switch 202, a first channel 203, a second channel 204, a signal processing unit 205, and an antenna unit 206. The components of the data transmission module are clearly defined, and the functional positioning of each unit within the module is clarified. The output of the image-data transmission unit 201 is connected to the input of the radio frequency switch 202. The output of the radio frequency switch 202 is connected to the inputs of the first channel 203 and the second channel 204, respectively. The output of the first channel 203 is connected to the signal processing unit 205, and the output of the second channel 204 is connected to the antenna unit 206 through the signal processing unit 205. The signal connection paths of each unit within the data transmission module are clearly defined, providing hardware connection guarantees for signal transmission and processing within the module, forming a complete image-data transmission module co-channel interference processing system. The signal control processing module 21 of this embodiment is used to determine the working state of the image data transmission unit 201 based on the radio frequency performance indicators fed back by the image data transmission unit 201, and to control the frequency switch 202 to turn on the second channel 204 if the working state of the image data transmission unit 201 is abnormal. Through the control of the signal control processing module 21, the frequency switch 202 is intelligently determined and controlled to achieve the switching between the first channel 203 and the second channel 204. The signal processing unit 205 of this embodiment is used to perform anti-interference processing on the radio frequency signal transmitted through the second channel 204, so that the antenna unit 206 can communicate with the UAV based on the anti-interference processed radio frequency signal. When switching to the second channel 204, it indicates that the working state of the image data transmission unit 201 is abnormal, and there may be co-channel interference. Therefore, anti-interference processing is performed on the radio frequency signal transmitted through the second channel 204 to ensure that the radio frequency signal for communication between the antenna unit 206 and the UAV is not affected by co-channel interference. Compared with related technologies, the embodiments of the present invention achieve independent control of multiple UAVs by judging co-channel interference and performing anti-interference processing, solving the problem of data transmission errors caused by co-channel interference. It does not require switching frequency bands, meets anti-interference processing requirements under all abnormal conditions, does not require spatial isolation, reduces the cost of anti-interference processing, and can transmit multiple high-definition videos or large amounts of data simultaneously, ensuring stable data transmission between UAVs and the ground terminal.

[0033] This embodiment provides a system for handling co-channel interference in image and data transmission modules. Figure 3 This is a schematic diagram of a second structure of a data transmission module co-channel interference processing system according to an embodiment of the present invention, as shown below. Figure 3As shown, the system includes: multiple data transmission modules 30 and a signal control and processing module 31; each data transmission module 30 includes an image-to-data transmission unit 301, a frequency switch 302, a first channel 303, a second channel 304, a signal processing unit 305, and an antenna unit 306; the output terminal of the image-to-data transmission unit 301 is connected to the input terminal of the frequency switch 302, the output terminal of the frequency switch 302 is connected to the input terminals of the first channel 303 and the second channel 304 respectively, the output terminal of the first channel is connected to the antenna unit 306, and the second channel 304 is connected to the antenna unit 306. The output of 04 is connected to the antenna unit 306 via the signal processing unit 305; the signal control processing module 31 is used to determine the working status of the image data transmission unit 301 based on the radio frequency performance indicators fed back by the image data transmission unit 301, and to control the radio frequency switch 302 to turn on the second channel 304 if the working status of the image data transmission unit 301 is abnormal; the signal processing unit 305 is used to perform anti-interference processing on the radio frequency signal transmitted through the second channel 304 so that the antenna unit 306 can communicate with the UAV based on the anti-interference processed radio frequency signal.

[0034] In some optional implementations, the radio frequency performance indicators include the drone's receive and transmit power indicators; the signal control processing module 31 includes a first judgment unit 311; the first judgment unit 311 is used to compare the drone's receive and transmit power indicators fed back by the drone receiver with a preset drone receive and transmit power threshold, and if the drone's receive and transmit power indicators are less than the preset drone receive and transmit power threshold, it is determined that the working state of the image data transmission unit 301 is an abnormal state, and if the drone's receive and transmit power indicators are greater than or equal to the preset drone receive and transmit power threshold, it is determined that the working state of the image data transmission unit 301 is a normal state.

[0035] In some optional embodiments, the signal processing unit 305 includes a signal amplification subunit 3051; the signal amplification subunit 3051 is used to amplify the transmission power of the radio frequency signal transmitted through the second channel based on the power amplifier, since the received transmission power index of the UAV is less than the preset received transmission power threshold of the UAV.

[0036] In some optional implementations, the radio frequency performance indicators include the ground-end received transmit power indicator; the signal control processing module 31 includes a second judgment unit 312; the second judgment unit 312 is used to compare the ground-end received transmit power indicator fed back by the map data transmission unit 301 with a preset ground-end received transmit power threshold, and if the ground-end received transmit power indicator is less than the preset ground-end received transmit power threshold, it is determined that the working state of the map data transmission unit 301 is abnormal, and if the ground-end received transmit power indicator is greater than or equal to the preset ground-end received transmit power threshold, it is determined that the working state of the map data transmission unit 301 is normal.

[0037] In some optional implementations, the signal processing unit 305 includes a noise reduction processing subunit 3052; the noise reduction processing subunit 3052 is used to amplify and suppress the radio frequency signal transmitted through the second channel 304 based on a low-noise amplifier when the ground end receiving transmit power index is less than a preset ground end receiving transmit power threshold.

[0038] In some optional implementations, the radio frequency performance indicators include the UAV received transmit power indicator and the ground-end received transmit power indicator. The UAV received transmit power indicator is the magnitude of the transmit power received by the UAV as reported by the UAV end, characterizing the signal strength received by the UAV end. The higher the transmit power received by the UAV end, the stronger the signal strength is generally. The preset UAV received transmit power threshold can be set according to the actual situation. The preset UAV received transmit power threshold is dynamically changing. For example, the preset UAV received transmit power threshold is set differently depending on the flight altitude of the UAV. The signal control processing module 31 selects the corresponding preset UAV received transmit power threshold according to the flight altitude of the UAV. In this embodiment of the invention, when the UAV received transmit power indicator is less than the preset UAV received transmit power threshold, it indicates that the signal strength received by the UAV end is weak and may be subject to co-channel interference. Therefore, the transmit power of the radio frequency signal transmitted through the second channel 304 is amplified by a power amplifier to improve the transmit power strength received by the UAV end.

[0039] In some optional implementations, the ground-end received transmit power index is the magnitude of the transmit power received by the ground end (data transmission unit 301), which characterizes the strength of the signal received by the ground end. The greater the transmit power received by the ground end, the stronger the signal strength is generally. The preset ground-end received transmit power threshold can be set according to the actual situation. The preset ground-end received transmit power threshold is dynamically changing. For example, the setting of the preset ground-end received transmit power threshold is different depending on the ambient noise of the UAV. The signal control processing module 31 selects the corresponding preset ground-end received transmit power threshold according to the ambient noise level of the UAV. In this embodiment of the invention, when the ground-end received transmit power index is less than the preset ground-end received transmit power threshold, the signal strength received by the ground end is weak, the ability to receive noise is weak, and it may be subject to co-channel interference. Therefore, based on the low-noise amplifier, the radio frequency signal transmitted through the second channel 304 is amplified and noise suppressed to improve the strength of the transmit power received by the ground end and reduce the impact of noise.

[0040] In some alternative implementations, such as Figure 4The diagram shows a schematic of the power amplification and noise reduction processing device, which is configured in the signal control and processing module 31. The power amplification and noise reduction processing device includes a multi-stage power amplifier, a low-noise amplifier, a transceiver duplexer, a low-pass filter, and a high-pass filter.

[0041] Among them, the multi-stage power amplifier is used to gradually amplify the power of the transmitted signal to ensure that the signal has sufficient strength to achieve long-distance transmission or coverage of a wider area; the transceiver duplexer is used to control the transmission and reception signals to share the same antenna, while avoiding interference from the transmission signal to the receiving link, and realizing the isolation and multiplexing of the transmission and reception signals; the low-pass filter and high-pass filter are used to filter the radio frequency signal, select the signal that meets the frequency requirements, filter out out-of-band interference and noise, and further improve the purity of the radio frequency signal; the low-noise amplifier is used to amplify the weak radio frequency signal, while minimizing the noise it introduces.

[0042] In this embodiment of the invention, if the received transmit power index of the UAV is less than the preset UAV received transmit power threshold, it indicates that due to co-channel interference, the transmit power received by the UAV is too low, leading to unstable data transmission. By amplifying the transmit power of the RF signal transmitted through the second channel using a power amplifier, the signal strength between the antenna unit and the UAV is ensured, preventing communication quality degradation or interruption due to insufficient transmit power. This effectively improves the communication stability and reliability of the UAV in complex interference environments. If the received transmit power index of the ground end is less than the preset ground end received transmit power threshold, it indicates that excessive noise results in insufficient transmit power received by the ground end, affecting data transmission stability. By amplifying and suppressing the noise of the RF signal transmitted through the second channel using a low-noise amplifier, noise interference is effectively filtered, increasing the strength of the transmit power received by the ground end and improving signal purity. This ensures the signal quality between the antenna unit and the UAV, avoiding communication errors and disconnections caused by insufficient receiving sensitivity. This significantly enhances the anti-interference capability and communication stability of the image-data transmission module in complex interference scenarios.

[0043] This embodiment provides a method for handling co-channel interference in image and data transmission modules, which can be used in the aforementioned image and data transmission module co-channel interference handling system. Figure 5 This is a flowchart of a method for handling co-channel interference in a data transmission module according to an embodiment of the present invention, as shown below. Figure 5 As shown, the process includes the following steps: Step S501: Based on the RF performance indicators fed back by the image data transmission unit, determine the working status of the image data transmission unit, and if the working status of the image data transmission unit is abnormal, control the RF switch to turn on the second channel.

[0044] Step S502: Perform anti-interference processing on the radio frequency signal transmitted through the second channel so that the antenna unit can communicate with the UAV based on the anti-interference processed radio frequency signal.

[0045] In some alternative implementations, the first channel is activated by controlling the frequency switch based on the normal operating state of the data transmission unit.

[0046] In some optional implementations, the radio frequency performance indicators include the drone's receive and transmit power indicators. The drone's receive and transmit power indicators fed back by the drone receiver are compared with a preset drone receive and transmit power threshold. If the drone's receive and transmit power indicators are less than the preset drone receive and transmit power threshold, the working state of the map and data transmission unit is determined to be abnormal. If the drone's receive and transmit power indicators are greater than or equal to the preset drone receive and transmit power threshold, the working state of the map and data transmission unit is determined to be normal.

[0047] In some optional implementations, the radio frequency signal transmitted through the second channel is amplified based on a power amplifier, since the received transmit power index of the UAV is less than a preset received transmit power threshold of the UAV.

[0048] In some optional implementations, the radio frequency performance indicators include the ground-end received transmit power indicator. The ground-end received transmit power indicator fed back by the map and data transmission unit is compared with a preset ground-end received transmit power threshold. If the ground-end received transmit power indicator is less than the preset ground-end received transmit power threshold, the working state of the map and data transmission unit is determined to be abnormal. If the ground-end received transmit power indicator is greater than or equal to the preset ground-end received transmit power threshold, the working state of the map and data transmission unit is determined to be normal.

[0049] In some optional implementations, based on the fact that the ground-end received transmit power index is less than a preset ground-end received transmit power threshold, the radio frequency signal transmitted through the second channel is amplified and noise suppressed using a low-noise amplifier.
