Popis:	In view of problem that low-pass decimation filter has big passband distortion and serious resource consumption in existing digital down conversion system, a digital down conversion system based on Simulink was designed adopting sharpening technique and interpolated second-order polynomial interpolation compensation filter, and system model was built by Simulink. The simulation results show that the system not only can reduce frequency and rate of signal, but also can effectively improve characteristics of decimation filter passband and stopband, and reduce workload of the system.
