Abstract

A programmable digital demodulation and analysis module is designed in this paper,it utilizes the cooperation of HSP50214B PDC and TMS320C5409 DSP to demodulate and analyze different kinds of modulated signals through software programming. Then an application of this kind of module in HF digital monitoring receiver system is presented.The experiments prove that this module is very applicable to radio receiver system.
