模仿程序matlab代码，WCDMA系统(模仿程序programming matlap)

说明：  MATLAB 前推回代法的配电网的潮流计算程序，适合于辐射性配电网和少环的配电网(MATLAB forward and backward substitution method of distribution network load flow calculation program, suitable for distribution network and less radiation distribution network ring)

程序的功能是：基于自适应在线遗传算法整定的PID控制(Functions of the program are: genetic algorithm based on adaptive online tuning PID control)

自抗扰控制器在实际使用时有多个需要整定的参数,由于控制器参数多,又无法确定参数作用方向,因此参数整定困 难,为实际使用自抗扰控制器带来不便。本文利用MATLAB软件仿真分析控制器及参数,寻求参数整定规律,简化整定过 程,对实际应用自抗扰控制器具有较大的意义(There ADRC in actual use multiple needs tuning parameters, as the controller parameters many, it can not determine the parameters of the role of direction, parameter setting sleepy Difficult to actually use ADRC inconvenience. In this paper, MATLAB software simulation analysis controller and parameters, parameter tuning laws seek to simplify tuning over Cheng, the practical application has a greater significance ADRC)

本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)
