Among them, the baseband signal generation subsystem is mainly responsible for the generation of the input modulation signal, the intermediate frequency signal generation subsystem is mainly responsible for converting the analog signal into a digital signal and filtering it, the digital-to-analog conversion subsystem is mainly used for converting the digital signal into an analog signal, and the filter subsystem is used for filtering the signal. Processing, the bypass attenuator subsystem is used to control the strength of the bypass signal, the synthesizer subsystem is used to synthesize and output the signals of various subsystems, and the DSP processor subsystem is used to process the signals and implement algorithms. This paper will introduce the system design ideas, flow charts, hardware design schemes in detail, and simulate and implement tests on the system.Keywords: Modulated hybrid sideband cancellation system, baseband signal generation, intermediate frequency signal generation, digital signal conversion, filter, synthesizer, DSP processor.
