说明：  通过matlab设计的GUI界面实现语音信号的实时录入和频谱分析和滤波等处理，并能够显示各阶段时域波形及频谱图，滤波器种类及参数可调(Through the GUI interface designed by matlab, the real-time input of speech signal, spectrum analysis and filtering are realized, and the time-domain waveforms and spectrograms of each stage can be displayed, and the types and parameters of filters can be adjusted.)

多电平差错概率在同一张图上仿真多幅度电平PAM在M=2,4,8，16时符号的差错概率，信噪比0:25(Multi-level error probability)

实现数据拟合，和多种方式的图形拟合与效果分析和统计检验(Data fitting, and a variety of ways graphical fitting and effect analysis and statistical tests)

基于matlab的判决反馈的均衡器，通过此程序可以了解均衡器的基本编程方法(This program can understand the basic programming methods equalizer matlab' s decision feedback equalizer)

判决反馈均衡器，前馈滤波器在频域实现，反馈消除干扰(DFE equaliter ，the forward filter is in frequency domain ，the feedback filter can estimate ISI )

该程序可以用于产生LFM信号，并输出在理想和加噪情况下分别经过匹配滤波器后的结果。(The program can be used to generate LFM signal, and outputs the noise in the ideal case and processing each of the results after the matched filter.)
