本文利用Simulink平台，模拟了一个小区内十个用户的码元发送，扩频，接收，解扩，判决的CDMA通信基本过程。(In this paper, the use of Simulink platform, simulation of a community within the 10 million to send the user' s code, spread spectrum, receiving, despreading, the verdict of the basic processes of CDMA communications.)

使用matlab实现了克里金插值算法，代码较短，运行时间也较为理想，但是缺少注释(use matlab to realize the Kriging interpolation algorithm ,code is shorter, running time is ideal)

Video Processing. Extract movie frame

基于粒子群的多峰值函数最优化方法，粒子群算法应用于多领域(PSO on muti-peak function)

2发2收，BPSK、QPSK、16QAM等多种调制方式下的差分空时编解码程序，仿真结果正确。(Two transmit antenna, two receiving antennas, a variety of modulation mode differential space encoding and decoding process, simulation results are correct.)

该例程是基于人耳掩蔽效应的语音增强算法的MATLAB实现。压缩包中附带参考文献（基于人耳掩蔽效应的谱减算法的研究与实现）、测试所使用的音频信号、以及段信噪比计算函数。源代码中MaskingSub.m（源代码主要部分）及Main.m为本人所写，其余均来自程序员联合开发网。运行环境MATLAB R2009b(Key words:masking property, spectral subtraction algorithm)

A Simple Digital Communication Receiver_2_

This file consists of matlab codes for a DEA optimization problem using fast algorithms of cplex

This code is an interesting version of noise production. this produced noise in controlled manner to display clouds. same code may be used to develop several natural random phenomenon

说明：  对信号进行zak变换，计算速度快结果准确，开发环境为matlab(Zak transform the signal to calculate speed and accurate results, the development environment for matlab)
