OFDM调制解调算法中的下变频算法以及matlab的实现方法(Down-conversion algorithm OFDM modulation and demodulation algorithm and MATLAB implementation)

说明：  一个很重要的程序包,里面包含很多程序, MATLAB码(UNIFORM is a MATLAB library which returns a sequence of uniformly distributed pseudorandom numbers. )

代码实现了超宽带基本定位算法，包括TOA,TDOA,以及TOA三维定位，所有代码已经在matlab 7.1下调试通过(The code is about basic positioning alogrithm of UWB,including TOA,TDOA and the 3d positioning of TOA,all of them is debuged successfully on matlab 7.10.)

本程序基于实测的LFM脉冲信号回波数据，进行脉冲压缩处理，实现MTI/MTD/Matched Filter等功能，主要完成以下具体功能 1.脉冲压缩的实现以及结果处理， 2.固定目标的对消的实现方法、作用以及必要性分析， 3，脉冲积累的时机、实现方式、效果及必要性分析， 4,动目标检测的实际含义、具体实现方案及结果分析， 5,对目标距离、速度、数量的回答及旁瓣抑制的必要性分析 ( This program echo LFM pulse signal based on the measured data, the pulse compression processing, realize MTI/MTD/Matched Filter, and other functions, mainly to complete the following specific functions 1. The realization of pulse compression and processing results, 2. Cancellation of the realization method of the fixed target, function and the analysis of the necessity, 3, the timing of the pulse accumulation, implementation method, effect and necessity analysis, 4, the actual meaning of the moving target detection, the concrete implementation plan and result analysis, 5, the target distance, speed, number of answer and the analysis of the necessity of the sidelobe suppression )

一些常用的MATLAB函数，求和； 求导数； 求极限；求泰勒展开式(Some commonly used MATLAB function, summation order derivative seeking limits order Taylor expansion)

matlab语言程序。采用Mallat重构算法提取出的暂态扰动波形(matlab language program. Mallat reconstruction algorithm using transient disturbance waveforms extracted)

measure the capacitance of parallel plate capacitor

说明：  本文件主要是针对于粒子群算法在matlab环境中地应用说编写地m文件！其中粒子群算法地目标函数可在源程序中自行更改！ -(this document is mainly targeted at PSO algorithm in Matlab environment application to the preparation of that document m! )

用matlab编写程序实现最优控制中的单纯形法。(Matlab programming with optimal control of the simplex method.)

旁瓣相消Sidelobe cancellation，抑制杂波，尤其在杂波较信号较强的情况下(Sidelobe cancellation Sidelobe cancellation, clutter suppression, especially in the strong clutter signal where more)
