Parallel FM Signal Demodulation System based on Software Radio Platform

A parallel FM signal demodulation system is designed in this paper.All FM signals from 90MHz to 110MHz could be captured, separated and restored into original information.The method of digital channelized receiving is used in the system to divide the broadband signals into independent ones according to their center frequency.This design could be used in the field of electron reconnaissance and multichannel communication system.We realized the design on a software radio platform based on the structure of SCA (Software Communication Architecture), and the advantages of this ideal is discussed in the paper.
