K-means聚类

MATLAB编写的利用u律函数实现的抑制OFDM峰均比的程序，程序通过运行，通过u率函数对信号压扩后，PAR明显降低(U law written by MATLAB functions for OFDM PAPR suppression program, the program by running through the u signal compression and expansion rate after the function, PAR was significantly lower)

说明：  QPSK解调的 MATLAB 实现 包括原chengxu和仿真(QPSK demodulation of the MATLAB implementation)

此程序用于语音信号的识别和在MATLAB 系统下的仿真，用于各种语音的识别！(The procedure for the voice of the identification of the procedure for the voice of the identification of matlab and the system of emulation, the voice of the!)

说明：  To support wireless communication : MIMO

have adapted the PSO to search in binary spaces

原函数及求得的相应差值多项式的函数的图像以及参原函数及求得的相应差值多项式的函数的图像以及参数alph的误差r数alph的误差r(原函数及求得的相应差值多项式的函数的图像以及参数原函数及求得的相应差值多项式的函数的图像以及参数alph的误差ralph的误差r)

说明：  一个关于联合对角化盲源分离算法的SOBI算法，非常好！！(One on the joint diagonalization for blind source separation algorithm SOBI algorithm, very good! !)

This a simple demonstration of a content based image retri using 2 techniques. 1. Using knn for image retri 2. Using svm for image retri .

自写曲率计算函数 ,关于非线性离散系统辨识，包含位置式PID算法、积分分离式PID。( Since writing the curvature calculation function, Nonlinear discrete system identification, It contains positional PID algorithm, integral separate PID.)
