本代码是基于MATLAB的停止等待arq机制的程序，使用MATLAB语言编写，实现STOP-AND-WAIT机制。-This code is based on the MATLAB-program stop and wait arq mechanism, using MATLAB language, to achieve STOP-AND-WAIT mechanism.

S变换在Matlab中对于信号处理方面的应用-S transform in Matlab for signal processing applications

Ｓ变换，ＭＡＴＬＡＢ 多分辨率分析可以从两个角度引入,函数空间的剖分和理想滤波器组,前者是首先提出的,数学上比较严谨,结论也比较全面。-S transform, MATLAB Multi-resolution analysis can be introduced two Angle, function space subdivision and the ideal filter group, the former is first proposed, math is rigorous
