introduction to mimo channels

说明：  无线移动通信中的MATLAB SIMULINK的代码，值得通信仿真人士一看 。(Wireless Mobile Communications MATLAB SIMULINK code, it is worth one watch those communications simulation.)

根据产生的BA无标度网路模型，计算其平均度分布，以观察模型性质(Produce the BA scale network model to calculate the average clustering coefficient, the nature of the observation model)

周期图法，bt进行功率谱估计，matlab仿真程序(Periodogram, bt power spectrum estimation, matlab simulation program)

包括各种规划问题的文档和程序，无约束优化，线性规划等等(Including planning documents and programs, unconstrained optimization, linear programming, etc.)

语音端点检测，有助于除去语音信号中的噪音部分，留下有用的携带信息的部分，有利于提取其中有用的语音特征参数，从而提高识别率。(Endpoint detection, helps remove the noise part of the speech signal, leaving useful information-bearing part, is conducive to extract the speech feature useful to improve the recognition rate.)

一个是用matlab实现指纹识别程序。里面附带指纹图片，并用其作为例子实现指纹图像的匹配。(One is to use matlab to achieve fingerprint identification procedure. Which comes with the fingerprint image, and use it as an example to achieve the matching fingerprint images.)

fm0 encoder and coder

说明：  实现图像的正反傅里叶变换，并用fft实现两幅图像的幅相交换(Amplitude and phase s replacement with fft)
