LINKDESIGN

说明：  我的收藏，协作通信中DF的matlab仿真 (My collection, collaboration, communication matlab simulation of the DF)

Ellipse of Concentration matlab function. The objective of the function is to compute and plot ellipse of constant probability density of error distribution.

这是一篇关于IPMSM的空间矢量调制的直接转矩控制系统的的优秀论文，理论推导详细，方案设计清楚，照着就能复现出来。值得参考。(This is an excellent paper on direct torque control system IPMSM space vector modulation of the theoretical derivation of detailed design is clear, according to the complex will be able to stand out. Worth considering.)

说明：  根据5G协议要求，产生5G NR下行链路信号，包含各种参考信号形式(According to the requirements of 5g protocol, 5g NR downlink signal is generated, including various reference signal forms)

详细介绍了用迭代法求解线性方程组的方法及其Matlab语言表示。(Iterative method described in detail with the method for solving linear equations and Matlab language said.)

Objective of the program is to solve for the steady state DC voltage using Finite Difference Method

多输入多输出系统，应用最小均方差均衡器的误码率性能曲线(Multi-input multi-output system, the application of the minimum mean square error equalizer BER performance curve)

说明：  对程序利用matlab对空时编码中的分集技术进行了仿真，通过对比采用分集技术和不采用此技术来进行性能分析(Matlab program for use on space-time coding techniques in the sub-set of the simulation, by comparing the use of diversity technology and do not use this technology for performance analysis)

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.)
