说明：  多输入多输出OFDM多用户检测仿真程序（MATLAB编写）(Multiple-input multiple-output OFDM multi-user detection simulation program)

transmission using uncoded bpsk modulated data

包括调制，解调，信噪比计算，欢迎大家下载学习，小波包分析提取振动信号中的特征频率。( Includes the modulation, demodulation, signal to noise ratio calculation, Welcome to download the study, Wavelet packet analysis to extract vibration signal characteristic frequency.)

新加入条件属性对决策属性的依赖度计算函数。基于粗糙集。(The new conditions for accession to the decision attribute attribute dependency calculation functions. Based on rough sets.)

用matlab工具编程实现快速kmeans算法，对数据进行快速的聚类(matlab kmeans )

This helps for writing Particle swarm optimization code

这时一个电磁场仿真程序，使用Matlab，编写了TM波的二维仿真程序，用FDTD方法(This is a simulation about two-dimensional of TM using the FDTD method)

最基础的灰色预测的matlab源程序，可以直接运行(Grey prediction program by matlab)

基于加权主成分分析（PCA）的人体检测算法，matlab程序(weighted PCA for pedestrian detection)

the file have a fft shift and hipass and lowpass filter and other options that works with signal .
