FM解调的性能分析与测试方法

Performance Analysis and Testing Method in FM Demodulator

在无线通信中,调频调制(FM)方式因其抗噪性能好、实现简单被广泛应用。分析了FM解调的信噪比性能,给出了一种FM解调信噪比的测试方法。

In wireless communication system ,F M has widespread use for its well antinoise perfor-mance and its simpleness.This paper analyses the SNR(signal -to -noise radio)of FM demodulation with elaborate theoretical derivation,and it gives out a testing method of FM demodulation SNR.
