Software radio is one of the wireless communication methods. In order to accurately receive IF software radio signals and ensure the reception and control effect of IF software radio signals, an IF software radio reception and control system based on DSP and switching chip is designed. Add digital signal processing chip and switching chip, design the radio receiver through the connection of oscillator, filter, mixer and other components, optimize the receiving controller by adjusting the logic control circuit, and generate and execute the receiving control command. With the support of the system hardware, DSP technology is used to collect and process IF software radio signals, calibrate the imbalance of radio signals, and realize the system's reception control function through modulation pattern recognition, demodulation and classification storage. The system test results show that under the control of the design system, the average signal-to-noise ratio of the radio received signal is up to 47.4dB, which can accurately receive the IF software radio signal, has a good IF software radio signal reception control effect, and effectively expands the radio reception range.
