With the Simulink simulation, BPSK BER performance measure, draw-bit signal to noise ratio and channel estimation mean square error of the curve, draw the signal to noise ratio and bit error rate curve, please explain in bit error rate 0.01, the two methods are combined performance of the different physical meaning. (2) frequency has been set up synchronization, a specific design of DS-CDMA single-stop sliding correlation method of time synchronization, simulation with Simulink (S-Function code their own way), analyze the design of time synchronization accuracy, draw bit signal to noise ratio and capture probability curve. (3) set time has been synchronized, a specific design of DS-CDMA frequency synchronization method, simulation using Simulink ()

一种极值搜索控制算法的matlab仿真程序，以一个非线性系统为控制对象，能够实现系统输出的极值控制(a extremum control algorithm matlab simulation program, in which a nonlinear system is controlled with its extreme output)

说明：  这个方案是非常基本的振幅调制和解调初学者实施。已作出评论。(This program constitutes of very basic amplitude modulation and demodulation implementation for beginners. Comments have been made. )

中心点漂移是一种非监督聚类算法（与k-means算法相似，但应用范围更广些),可用于图像分割，基于Matlab实现的源码。 MedoidShift is a unsupervised clustering algorithm(similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.(Center drift is a non-supervised clustering algorithm (k-means algorithm with the similar, but more a wider range of applications), can be used for image segmentation, based on the realization of the source Matlab. MedoidShift is a unsupervised clustering algorithm (similar to k-means algorithm, but can be used in border application fields), can be used for image segmentation. Included is the Matlab implementation source code.)
