matlab基于无线蜂窝系统的仿真的应用，非常强大，非常全面，值得下载应用！(matlab simulation applications based on wireless cellular systems, is very powerful, very comprehensive, it is worth the download application.)

使用matlab计算输入信号的卷积快速卷积，对卷积的原理进行说明(conv)

一个帮助外汇交易者判断交易方向的信号，思路是进行突破交易，结合布林带通道和KD指标，KD上涨过程中过滤做空信号，KD下跌过程中，过滤做多信号。(A signal to help foreign exchange traders to judge the transaction direction, train of thought is a breakthrough deal with Bollinger channel and KD index, filter the short signal KD increases, KD falls in the process, filtering the signal to do more.)

此例程为配套书籍的第六章例题7-15的相对应代码，功能为PCM编码，编程环境为matlab。(This routine supporting books Chapter Example 7-15 corresponding to the code, the function for PCM coding, programming environment Matlab.)

说明：  matlab的一些简单使用，口输入不加扩展名的文件名，该文件必须在当前搜索路径中，例如输(matlab)

这是用MATLAB做的三维立体图。。。。。。。。(This is done using MATLAB three-dimensional map. . . . . . . .)

SPECFEM2D，模拟二维各向异性粘弹性介质的地震波传播。(SPECFEM2D simulates seismic wave propagation in two-dimensional anisotropic viscoelastic or coupled viscoelastic-acoustic media.)

关于MATLAB的一个很好的PPT。讲的是符号运算。对于初学者很好。页面也很漂亮。(MATLAB on a good PPT. Talking about the symbolic operation. Good for beginners. Page is also very beautiful.)

说明：  在matlab上面实现升余弦滤波器设计，不是用的matlab函数(In achieving the above raised cosine matlab filter design, not by the matlab function)
