随机调制信号下的模拟ppm，单径或多径瑞利衰落信道仿真，处理信号的时频分析，有较好的参考价值，FIR 底通和带通滤波器和IIR 底通和带通滤波器，有小波分析的盲信号处理，采用偏最小二乘法，利用matlab GUI实现的串口编程例子。-Random ppm modulated analog signal under Single path or multipath Rayleigh fading channel simulation, When processing a signal frequency analysis, There are good reference value, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter, There Wavelet Analysis Blind Signal Processing, Partial least squares method, Use serial programming examples matlab GUI implementation.
