## 3. FM 仿真(MATLAB Communications Toolbox) MATLAB 的 [Communications Toolbox](Communications Toolbox) 中提供了 FM 调制函数 [fmmod](Frequency modulation - MATLAB fmmod - MathWorks 中国),高斯白噪声函数 [awgn](ww2.mathworks.cn/help/c),以及 FM 解调函数 [fmdemod](Frequency demodulation - MATL...
根据遥测系统脉冲编码调制/调频(PCM/FM,Pulse Code Modulation-Frequency Modulation)信号的特点,采用基于多相滤波的解调方法.该方法通过多相滤波的方式来实现正交变换,不需要在接收端恢复同频同相的载波,从而降低 了传统解调方法中电路实现的难度.通过MATLAB对信号进行调制解调的仿真,比较了不同解调方法对信号的解调效果...
