Matlab-introduction

随机产生100个字母，并统计元音与半元音字母个数(Randomly generated 100 letters and vowels and semi-vowels statistical number of letters)

用振幅为0.8的方波进行傅立叶分析，并用分析得到的系数求解当K取不同值时的合成信号( F = FOURIER(f) is the Fourier transform of the sym scalar f with default independent variable x. The default return is a function of w. This example is useful for the persons who learn sth about signal processing.)

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.)

说明：  模拟缉私船追击变速走私船 加速到一定的速度，经过多久追上 并画出轨迹图！(Simulate how long it takes for the anti-smuggling vessel to chase the variable speed smuggling vessel to accelerate to a certain speed and draw the trajectory chart!)

说明：  LMS算法的语音信号处理方面的仿真，也是我毕业论文中的(LMS algorithm for speech signal processing simulation)
