MATLAB语音处理的函数工具箱，为语音处理提供基本函数(MATLAB toolbox voice processing functions, provide basic functions for the voice processing)

用于图像配准等应用的互信息计算，为Matlab程序，比较简单，但很实用。(for image registration applications such as the mutual information, as Matlab procedures are relatively simple, but practical.)

利用Matlab软件，建立QPSK基带传输系统，比较AWGN和Rayleigh信道下的系统BER性能。代码比较短，是老师布置的仿真作业，有同样需要做仿真的同学，可以下载下来看看，把理论和仿真画在了一张图上。

说明：  这是一个在matlab中调用bioperl函数的算法示例(This is a matlab function to call the algorithm bioperl sample)

In this project, the standard particles swarm optimization - named here (MyPSO) is simulated and tested by five well-known benchmark functions (Sphere, Ackley, Rastrigin, Rosenbrock and Schwefel p2.26). Then, a new mechanism- named here (Improved MyPSO) is introduced to improve the performance of the standard particles swarm optimization to achieve better results and avoid stagnation at bad results. This new mechanism is also tested by the same benchmark functions. The results of improved PSO are then compared with those of standard PSO and different published improved PSO (SPSO, PSO-XD, CPSO-S and PSO-P5).
