matalb编写的语音编码的有关程序，有兴趣的可以下载(matalb prepared speech coding procedures are interested can download)

it contains report ,matlab codes for PAPR ofdm reduction techniques like SLM,PTS methods.all are working.

基于MMSE均衡的BPSK信号BER的分析与系统性能分析( BPSK signal BER analysis uising MMSE equalization )

This is the source code for a Single Vector Machine classifier, briefly called a SVM classifier. There are 60 peices assigned for training and 30 for testing the classifier.

说明：  这是现代信号处理领域最常用的信号分析方法！(this modern signal processing is the most commonly used method of signal analysis!)

通过仿真,分析了多径效应和多普勒效应的原理.并给出了移动信道的建模方案和程序.每个结论都给出了仿真程序可直接运行.(through simulation, Analysis of the multi-path effects and the principle of Doppler effect. and gives the mobile channel modeling programs and procedures. Conclusion gave each a simulation program can run.)

客体复原代数重构算法的matlab实现。(Algebraic reconstruction algorithm object recovery matlab implementation.)

在做优化的时候，起初选择了GA算法，但是GA的不稳定性（或者陷入局部最优）实在让人抓狂，前后两次的结果相差竟然有时候能达到30 以上，当时由于时间的原因，我只好选择了优化1000次，然后以其中的最小值最为最佳方案。虽然问题也算解决了，但是从学术上将，这种奔方法是让人很尴尬的。所以，我从网上下载了一个GA－PSO算法，试着利用GA和PSO组合的策略进行优化，结果算法很问题，效率和不错。我下载原始算法，有一个问题就是它是针对所有的设计变量上下限都是一样的，所以我对程序进行了修改与改进，现在可以处理上下限不一致的问题，同时fix了一些bug。现在把修改后的程序和大家分享一下，希望能对您有用.注意myfit需要用自己的函数，否则出错，因为我的myfit程序在调用过程中，需要使用matlab的Kriging工具箱 (a optimization method combining GA and PSO)
