基于MATLAB的turbo码的仿真研究(MATLAB-based Simulation of turbo codes)

说明：  频分复用(FDM，Frequency Division Multiplexing)的matlab实现，仿真时录入三路声音信号进行处理，将用于传输信道的总带宽划分成三个子频带，经过复用以后再将录入的声音信号恢复出来。(FDM (frequency division multiplexing) is realized by MATLAB. In the simulation, three sound signals are input for processing. The total bandwidth used for transmission channel is divided into three sub bands. After multiplexing, the input sound signals are recovered.)

独立分量分析，利用此程序可以提取独立分量(independent component analysis, the use of this procedure can be extracted ICA)

论坛上找的，很多内容，都是以FUNCTION形式呈现，希望对大家有帮助(Forum looking for, many elements are present in the form FUNCTION, we want to help)

Matlab的FFT算法程序 里面有基2时间抽取的FFT 还有基2频率抽取的FFT (Matlab' s FFT algorithm which has taken the time base 2 radix-2 FFT have taken the FFT frequency)

這是一個讓原始音訊可以再不改變音訊長度下，改變pitch的程式，因為如果音訊用resample，雖然可改變其音訊頻率音高，但是卻會有拉長音訊的副作用，因此設計了一個可以改善其缺點的小方法(實做paper ）(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))

This is a program for Binary Genetic Algorithm

为matlba GUI中axes控件添加了放大，平移等功能(offer the funcion of scale, move and so on to the axes in GUI of matlab)

simulink环境下的三相NPC（中性点钳位）逆变器的仿真模型(simulink environment three phase NPC (neutral point clamped) inverter simulation model)

为配合新一代天气雷达应用与开发的需要，现将新一代天气雷达（CINRAD/SA、CINRAD/SC、CINRAD/SB、CINRAD/CB、CINRAD/CC、CINRAD/CD的原始数据格式和拟采用的统一数据格式以及读取程序挂在网上，供大家下载(read Doppler radar data, the process of the SA-Doppler weather radar on the original scan data processing)
