本文介绍了一种基于自适应滤波算法的语音信号增强处理的方法。文中在扼要介绍了目前常用的语音增强方法的基础上，重点介绍了采用LMS算法的自适应语音增强系统。对三种LMS算法（基本LMS算法,符号误差LMS算法及NLMS算法）进行仔细研究，并用Matlab仿真实现，验证比较了三种算法的语音增强效果。(In this paper, a system of speech enhancement is discussed based on self-adaptive algorithm. On the basis of presenting an overview of a number of speech enhancement is described in detail based LMS algorithm.This paper researches sorts of LMS algorithms（the basic LMS algorithm,the sign error LMS algorithm and NLMS algorithm） in detail, and compares the three algorithm of speech enhancement effect with Matlab simulation validation.)

BPSK载频估计，用它的平方谱和四次方谱进行估计，能够在0dB情况下完成有效估计(BPSK carrier frequency estimation, with its squared spectrum and quartic spectrum estimation can be completed in the 0dB case valid estimation)

说明：  遗传算法序列（GA）（全）利用matlab编写遗传代码 很有用的啊(Sequence of genetic algorithms (GA) (wide) the use of the preparation of the genetic code matlab useful ah)

OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

adaboost算法的一个简要编程,对于训练算法能有一个很好的初步指导作用(AdaBoost algorithm is a brief program for the training algorithm can have a good initial guide)

This project has proposed an alternate novel method of finger vein and finger texture recognition system .This system has taken more advantage than the existing system in term of security purpose since the vein pattern is not visible to human vision without any special device, it will not produce any trace in any object. We examined a complete and fully automated approach for the identification of low-resolution finger surface / texture images for the performance improvement

说明：  particle swam optimazation technique
