采用eigen value来模拟各种衰落信道的源码程序，可以仿真瑞利衰落和AWGN叠加等等的情况。有详细注释。(Eigen value used to simulate a variety of fading channel the source program, you can simulation superimposed Rayleigh fading and AWGN and so on. Has detailed notes.)

自动画圆小程序 ：只要有了坐标，就可以方便的大量快速画圆(Automatic Circle applet: As long as with the coordinates, you can quickly draw a circle to facilitate a large number of)

说明：  升余弦滚降信号及其功率谱。可以通过它实现通信系统中常用的升余弦滚降系统。用处极大哦~(Raised cosine roll-off signal and its power spectrum. Can achieve through its communication systems commonly used raised cosine roll-off system. Oh ~ great usefulness)

稳健的波束形成算法，处理在误差条件下稳健的自适应波束形成算法(robust beamforming)

数值方法解方程组AX=B（LU分解），过程分3步，首先，分解系数矩阵A=LU，然后，解LY=B，最后再求UX=Y 另一种是直接求解的（2.1）(Numerical method to solve the equations AX = B (LU decomposition), 3 step process, first of all, the decomposition of the coefficient matrix A = LU, then, Xie LY = B, and finally seek UX = Y another directly solving (2.1 ))

非常完整的关于时频分析的所有程序，包括小波变换，短时傅里叶变换，gabor变换等等(the matlab tools include many programs about time frequency,such as gabor transform,STFT,wavelet transform,and so on )

`1-magic : Recovery of Sparse Signals via Convex Programming

说明：  matlab的几个经典程序，有100的。(matlab several classical procedures, has 100.)

说明：  改变输入信号电平从1~6，对这6种情况分别进行仿真并计算其超调量mp，将其绘制在同一张图中进行比较.(gai bian shu ru dian pin qiu chao tiao)
