YBUS FORMATION IN POWER SYSTEM

3phase fault in induction motor

实现基于BPSK的直接扩频信号调制，并显示出各阶段信号波形。(Direct-based BPSK modulated spread spectrum signal, and shows the signal waveform of each phase.)

研究生时的现代信号处理的作业，数据模型归一化，模态振动，鲁棒性好，性能优越，数学方法是部分子空间法，使用大量的有限元法求解偏微分方程，搭建OFDM通信系统的框架。(Modern signal processing jobs when the graduate, Normalized data model, modal vibration, Robustness, superior performance, Mathematics is part of the subspace, Using a large number of finite element method to solve partial differential equations, Build a framework OFDM communication system.)

求一维序列x(n)的离散Fourier谱分析，s(0:m)离散功率谱，c(0:m)振幅谱，cta(0:m)位相谱，其中m=[n/2.]。(Discrete Fourier spectrum of one-dimensional series)

This file is about vector control of permanent magnet synchronous machine. You must try it

基于Pareto支配的多目标粒子群算法程序，用matlab设计实现，已经通过多个公认测试函数测试，结果良好。 (Based on multi-objective particle swarm algorithm Pareto domination, using matlab design implementation, test function has been recognized by a number of tests with good results.)

语音激活检测，可以检测每帧是语音信号还是静音，MATLAB实现。(Voice Activity Detection with MATLAB.)

Spread Spectrum Watermarking MATLAB

matlab 自己学习的,可以提高matlab编程(matlab,impove your matlab ability)
