用matlab实现三级小波分解，希望对初学者有所帮助(Using matlab to achieve three wavelet decomposition, want to be helpful for beginners)

说明：  基于matlab的通信系统仿真系列。A simulated oscilloscope and a simulated spectrum analyzer。供刚接触到matlab通信系统仿真的朋友使用。(Matlab-based communications system simulation series. A simulated oscilloscope and a simulated spect rum analyzer. Matlab for the counting of the communications system simulation using friends.)

权重改进的粒子群算法，来自于《精通MATLAB最优化计算》(pso with improved weighted factor)

说明：  一个简单的遗传算法（GA）入门程序，附有详细的说明，适合初学者入门使用。(A simple genetic algorithm (GA) entry procedures, with detailed description of entry for beginners to use.)

ford-fulkerson算法，通过标号寻找网络最大流(ford-fulkerson algorithm )

说明：  挠性转子的平衡原理是建立在弹性轴（梁）横向振动理论的基础上，其动平衡原理为：挠性转子在任意转速下回转时所呈现的动挠度曲线，是无穷多阶振型组成的空间曲线，其前三阶振型是主要成分，振幅较大，其他高阶振型成分振幅很小，可以忽略不计。(Flexible rotor balancing principle is based on the elastic axis (beam) on the basis of transverse vibration theory, the balancing principle is: flexible rotor turning at any speed when the deflection curve presented is composed of infinite number of vibration modes space curve, the first three modes is the main component, the larger the amplitude, the amplitude of the other components of higher modes is very small, can be ignored.)

本书介绍的是MATLAB中SIMULINK的应用,在通信仿真中用处还可以把(The book is described in the SIMULINK of MATLAB applications, the usefulness of simulation in communication can also be used to)

在通讯系统中，可以计算一个信号的SNR,THD等(In communications systems, can calculate a signal s SNR, THD, etc.)

求信号的幅度谱和相位谱,用matlab画出波形比比较(work out the amplitude and phase spectrum of a signal)

说明：  MATLAB新手学习常见的两百个问题，非常实用。(MATLAB novice learning common 200 problems, very practical.)
