algorithm for near and far fields

利用功率谱估计及ＩＦＴ数字滤波及短时傅里叶变换等手段对声音信号进行处理(Use of the means of power spectrum estimation and IFT digital filtering and short time Fourier transform , such as the sound signal processing )

说明：  计算香浓信息熵，方便快捷的matlab代码，可以简单直接调用(Calculated Shannon information entropy, convenient matlab code can be simple and direct calls)

本人长期从事matlab中simulink在无线通信上的仿真（通信抗干扰国家重点实验室），此Turbo迭代译码程序是我见过的最经典的链路，过程非常的清晰，尤其迭代译码部分巧妙的利用降速率用最简单的结构实现了复杂的迭代过程，值得同行学习，必有极大收获！(err)

总结了自己关于通信原理学习的一下认识,希望大家多交流(about Communication Fundamentals in my side)

用于实现森林防火隔离带的计算和画图 我用MATLAB编的程序，存为txt文档格式，方便大家查看。这是我们组在学校国际赛选拔赛时编的程序，用于实现森林防火隔离带计算和画图。可立即执行。(Forest Fire Barrier used to implement the calculation and drawing program I use MATLAB code, save it as txt file format to enable easy viewing. This is our group in the school when the series of international competitions qualifying procedures for the realization of Forest Fire Barrier calculation and graphics. Can be implemented immediately.)

基于LMS的时延估计算法LMSTDE，改方法的改进版本为ETDE算法，会在稍后上传(Time delay estimation algorithm based on LMS LMSTDE, change the method of an improved version of the ETDE algorithm, will be uploaded later)

带Simth补偿的模糊PID控制器设计及仿真(Simth compensation with the fuzzy-pid controller design and simulation)

利用传统有限元方法计算二维possion 方程的特征值问题，网格采用的是三角网格，由matlab 的pdetool产生，一次多项式近似(Using traditional two-dimensional finite element method possion equation eigenvalue problem, the grid uses a triangular mesh is generated by the matlab pdetool, a polynomial approximation)

连续相位调制信号(CPM)产生，小波包分析提取振动信号中的特征频率，可以实现模式识别领域的数据的分类及回归。( Continuous phase modulation signal (CPM) to produce, Wavelet packet analysis to extract vibration signal characteristic frequency, You can achieve data classification and regression pattern recognition.)
