小波包变换可以对高频部分提供更精细的分解，而且这种分解既无冗余，也无疏漏，所以对包含大量中、高频信息的信号能够进行更好的时频局部化分析。(Wavelet packet transform can provide the high frequency part of the finer decomposition, and this decomposition is neither redundant nor oversight, so the signal contains a large amount of high frequency information can be a better time-frequency localization analysis.)

STBC Development in mimo ofdm

实现极大值查找，可输出数值和下标，并带有阈值功能。(search for maximum value)

实现了小波变换的阈值去噪算法，并实验仿真对比去噪效果(Internship wavelet threshold de-noising algorithm,)

这是一种十分常见的简单的MINO阐述的新方法的MATLB代码，基于这种方法可以极大的减少误码率和码间干扰。(This is a Matlab code of a very popular and simple transmit method based on MINO system. By using it, the BER can be greatly redused.)
