matlab从入门到精通，本书主要介绍matlab的基础知识和提高的内容(matlab from entry to the master, this book introduces the basics of matlab and improve the content of)

DTMF 的 matlab 仿 真 实 现(DTMF implementation of matlab simulation)

matlab的一些应用程序，适合有一定基础的人使用 (Matlab some applications, a basis for the use of)

QPSK调制与解调在matlab平台上的实现。能以图形的方式显示其工作过程以及计算相应的误码性能。(QPSK modulation and demodulation in Matlab platform is realized. In a graphic display of their work process and the corresponding calculation of the error rate performance.)

相关函数法该方法先由序列估计出自相关函数R，然后对其进行傅立叶变换，得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.

说明：  k-均值聚类算法c语言版，经验证测试是可以运行

IT IS THE CODE OF GENETIC ALGORITHEM WHICH IS DEVELOPED IN MATLAB SOFTWARE

瑞丽衰落和莱斯衰落的对比 瑞利衰落（Rayleigh Fading）：在无线通信信道中，由于信号进行多径传播达到接收点处的场强来自不同传播的路径，各条路径延时时间是不同的，而各个方向分量波的叠加，又产生了驻波场强，从而形成信号快衰落称为瑞利衰落。瑞利衰落属于小尺度的衰落效应，它总是叠加于如阴影、衰减等大尺度衰落效应上。(rice fading and rayleigh fading)
