很好的OFDM的基于MATLAB的仿真程序包，且包含了最终结果图.(montecarlo type montecarlo in the command window and wait for a long time.. _simulation of the complete OFDM system. _use of a very large file in order to get probabilities. _loop over different value of the noise. _compute the SNR for each value of the noise. _provide the SNR/BER plot. if you are in a rush : simulation_system !! go into the right folder and type simulation_system in the command window. _then type the value of the noise power (range = [-20,10]) _the function provides the channel estimation, the bit allocation, and a plot illustrating the errors. _this is a fast function (less pilot, no synchronization, small file).)

回归轨道卫星，回归周期1天，倾角分别为60度，周期为4h。(Orbit satellites, one day return period, inclination of 60 degrees and a period of 4h.)

设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)
