说明：  利用时域有限差分（FDTD）仿真二维（2D）横磁波（TM）的传播，吸收边界条件为完全匹配层（PML）。(The use of finite difference time domain (FDTD) simulation of two-dimensional (2D) transverse magnetic (TM) the spread of absorbing boundary conditions for the perfectly matched layer (PML).)

very nice jornal with code in sites

Simple Evolutionary Algorithms from a Chapter of book published by Springer

说明：  EM算法实现，对于需要的朋友来说还不错的，(EM algorithm, for a friend in need is also good,)

自适应信号处理，英文版的！！史坦福大学Bernard Widrow写的(Adaptive signal processing, the English version! ! Written by Bernard Widrow Stanford University)

filtered back projection

燃料电池模型基于simulink，十分有用(Fuel cell model is based on simulink)

自己写的包络谱函数，可以实现对时间序列求出他的功率谱(Write their own spectral envelope function, can realize to the power spectrum of his time sequence)

可以计算ofdm系统和F-ofdm系统下的误码率与信噪比变化(The error rate and SNR of OFDM system and F-ofdm system can be calculated)

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.)
