MIMO的研究越来越成熟，而大规模MIMO在未来是研究的热点。了解一般MIMO的容量等特性，将有助于理解和掌握。(MIMO research and more mature, but large-scale study of MIMO is a hot spot in the future. For general MIMO capacity and other features, will help to understand and master.)

一个很有用的程序，音频信号通过LM386放大，小波包分析提取振动信号中的特征频率。( A very useful program, LM386 audio signal amplification, Wavelet packet analysis to extract vibration signal characteristic frequency.)

使用对称帧差法提取运动模板，后结合背景帧差提取运动目标，二者结合进行逻辑运算，得到最终的运动目标；内部含有一个单独的函数，用于背景重构(Extracted using the symmetric difference motion template frame, combined with the background of the frame difference after the extraction of moving objects, a combination of both logic operations, the final of the moving object inside with a separate function, for background reconstruction)

it includes some usefull codes in speech processing
