说明：  采用10阵元的阵元间距为1/2波长的均匀线阵，估计两个不相干的信号源的波达方向。假设信号 源分别来自 和 方向，信噪比分别为10dB和20dB；并假设样本数为100。使用music算法实现DOA估计(music algorithm used for doa estimation)

数字信号处理与题解。DSP理论入门电子书，书中有简单的Matlab编程，以及简单的滤波器设计(Digital signal processing and problem solution. Introduction to DSP theory book, the book has a simple Matlab programming, and simple filter design)

Matlab 关于维纳滤波器的设计问题，其中包括一阶维纳滤波器参数，性能分析(Matlab on the Wiener filter design problems, including a first-order Wiener filter parameters, performance analysis)

看了一段时间的3GPP的信道建模，所以自己动手写了一个（参考了该协会的标准代码，不过改良了一些，执行效率更高）(the 3GPP SCM model building. Comparing to the original code, this task is more efficient and clearer.)
