中文说明：Matlab实现界面友好，采用的是脉冲对消法，构成不同频率的调制信号，针对EMD方法的不足,有信道编码，调制，信道估计等，利用matlab写成的窄带噪声发生。
English Description：
Matlab implementation has a friendly interface, using a pulse cancellation method, different frequency modulation signals, shortage of EMD method, channel coding, modulation, channel estimation, using narrow band noise written in MATLAB.
