QPSK-PLC-Simulation

LTE系统中协同通信的三种协同策略比较。AF/DF/CC，里面有详细的程序，适合初学者。(Three kinds of collaborative strategies of communication in cooperative LTE system. AF/DF/CC, which has detailed procedures, suitable for beginners.)

It works very well in Matlab and is very efficient

Time series statistical analysis, used to obtain various statistics,include Variance Median The maximum value The minimum value Standard deviation Skewness Kurtosis Jarque-Bera test Concomitant probability of Jarque-Bera test

智能天线技术，里面介绍了很多关于频域宽带波束形成方面的算法。作者L.C Godara是这方面的大牛，发表了很多关于波束形成方面的paper，大家可以参阅一下。(Smart antenna technology, which introduces a number of algorithms on the frequency domain broadband beamforming aspects. The Author LC Godara large cattle in this area, published a paper about the many aspects of beam forming, we can see it.)

说明：  利用Matlab语言实现三次样条曲线，并且有GUI图形显示，是数值分析的基础(THE code use Matlab，come ture spline )

说明：  均匀线阵情况下的，相干信号的产生，并不是入射后的信号，而是原始的相干信号，希望各位不会搞错(Uniform linear array case, the coherent signal generation, not the signal after the incident, but the original coherent signals and hope that will not be wrong)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

波束形成也称为空域滤波，即通过一定布置的空间阵元对空间信号场进行采样，然后经过加权处理得到期望的输出结果。(failed to translate)

通用路径损耗模型包括Log-distance/normal shadowing计算(General Path Loss Model, including log-distance/normal shadowing path loss model)

DOA估计（雷达来波方向估计）是雷达的重要理论，我提供了阵列信号处理中基于MUSIC算法的DOA估计，和基于最大熵法的DOA估计的MATLAB源代码。都是自己仿真用的。(err)
