基于matlab实现ldpc码的编解码和性能分析

Differentiation of the Gaussian pulse

These are MATLAB codes for implementing Chebyshev-Type 2 Bandpass and Bandstop filters.

通过史密斯圆图进行相关计算 求得输入阻抗( Correlation calculation determined by the input impedance Smith chart)

压缩感知OMP算法，稀疏基为2-d小波基，包含两种算法：1、先稀疏再采样；2、先采样再稀疏；该压缩包对刚接触压缩感知的初学者有非常重要的意义。(compressived sensing OMP)

此程序实现sinc函数的绘制，在自适应波束形成里可以视为波束图(This process of mapping implementation sinc function in adaptive beamforming can be regarded as a beam map)

说明：  蚁群算法，最基本的，有效的解决TSP问题(Ant colony algorithm, the most basic and effective problem solving TSP)

利用matlab将excel文件中的数据导入或导出，介绍相应函数的用法(Using matlab to excel file import or export data to introduce the usage of the corresponding function)

matlab实现对ofdm系统的整体仿真，适合初学ofdm的人员(Matlab implementation of the overall simulation of the OFDM system, suitable for the beginners of OFDM)

dc-dc buck电路，仿真效果较好，偏差控制的很小，pi效果不错(DC-DC buck circuit, simulation effect is good, deviation control is very small, PI effect is good.)

一个外国人Anton Zaicenco 2004年开发的一个有限元工具箱，实在Matlab环境下开发的。里面有多个例子，可以向Matlab工具爱好者展现她的有限元分析特点和技巧。(FEM analysis toolbox for solid mechanics. Project started: Aug 2004 Anton Zaicenco )
