Abstract

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