说明：  提出了一种综合采用ButterWorth低通滤波器和平均值低通滤 波器的低通滤波器设计新方法. (Presents a comprehensive low-pass filter and using ButterWorth average low-pass filter low-pass filter design of the new method.)

Spread Spectrum Multiple Access Communications

vq矢量量化，对说话人进行识别，内置有语音样本，识别率高达90 。对语音信号进行读取，预处理，特征参数提取，向量量，训练，对比识别。(vq vector quantization for speaker identification, built-in voice samples, the recognition rate of 90 . Read the speech signal, preprocessing, feature extraction, the amount of vector, training, recognition comparison.)

这个是用来计算Haar-like特征数目的，用MATLAB求的某一个矩形特征的数目(This is used to calculate the number of Haar-like features, with the MATLAB find a certain number of characteristics of a rectangular)

For a given array of angles, determines which are within the bounds, accounting for wrap around

基于YUV格式的视频做的数字视频水印，该算法可到达很好的健壮性和透明性(YUV format video, digital video watermark, the algorithm can reach a good robustness and transparency)

apf的谐波检测 利用瞬时无功理论搭建开环和闭环检测环节的simulink仿真(Simulink simulation of harmonic detection of APF theory to build the open-loop and closed-loop detection process using instantaneous reactive power)
