摘要
本文介绍了中频PCM/FM信号全软化FM解调系统的组成、解调原理及软件解调的一种实现方法,完成了对软件解调算法的理论阐述和数学推导,并根据推导出的数学模型在Matlab平台下进行软件设计,最后进行了仿真测试和实验验证,仿真结果和实验结果证明了该实现方法的可行性。
An implementation method of software demodulation according to the theory of PCM/FM Interm ediate Frequency signal's software FM demodulation is introduced. The expatiation of theory and the deduction of equations are accomplished. The software is designed on the Matlab platform with the mathematical model. Computer simulation and experiment prove the feasibility of this implementation approach.
