Embodiment 1

[0038] Such as figure 1 As shown, a multi-channel signal processing device includes a baseband processing module and a radio frequency processing module;

[0039] Baseband processing module, including FPGA, ARM and peripheral interface;

[0040] Peripheral interface, including FMC interface, HDMI port, SD card socket, network port and USB port;

[0041] As the core of data processing, FPGA and ARM are transmitted through the expandable interface AXI bus;

[0042] FPGA configured to control data processing and channels;

[0043] ARM configured for joint processing of data and data interaction with a user manipulation interface;

[0044] FMC interface, configured as a communication channel for FPGA and AD9361 chip;

[0045] The HDMI port is configured to connect to the display screen, which can display and view the operating system in ARM;

[0046] The SD card socket is configured for plugging and unplugging the SD card, where the SD card can realize the programming of the ...

Embodiment 2

[0059] On the basis of the above-mentioned embodiment 1, the present invention also mentions a multi-channel signal processing method, which specifically includes the following steps:

[0060] Step 1: Configure the low-noise amplifier, mixer, low-pass filter, ADC, and DAC in the RF processing module through FPGA to make them work normally;

[0061] Step 2: After the two receiving channels in the AD9361 chip receive the signal, they are sampled, and then the data is transmitted to the FPGA through the FMC interface;

[0062] Step 3: The AD bit width of the AD9361 chip is 12 bits. After zero padding, the data is pieced together into 32 bits and sent to ARM through the AXI bus;

[0063] Step 4: ARM reads the data in real time and transmits it to the network port, and the user control interface performs real-time analysis after receiving the data to realize the signal analysis and demodulation function of the Internet of Things;

[0064] Step 5: The user control interface sends t...

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a multi-channel signal processing device and method. Background technique [0002] At present, with the development of communication, the Internet of Things technology has been developed. Since the test of the Internet of Things signal has many scenarios and takes a long time, it has high requirements for the size and power consumption of the signal processing device. Meet the characteristics of outdoor operation. The previous signal processing devices were single-processed, and the size of the whole machine was large, so it was difficult to meet the characteristics of outdoor operation, and it did not meet the requirements of transmitting and receiving IoT signals at the same time. Contents of the invention [0003] Aiming at the above-mentioned technical problems existing in the prior art, the present invention proposes a multi-channel signal processing...
