This system consists of QPSK modulation and demodulation, IFFT modulation, space time coding and decoding, based on training symbols such as communication channel estimation module.)

均值，高斯，中值滤波器自编，并附带边界的处理项，最后是一个test.m得检测功能文件(Mean, Gaussian, median filter self, and to deal with border entry, and finally the detection of a test.m may file)

matlab 遗传算法GA，粒子群算法PSO,蚁群算法AS 前段时间上智能计算方法实验课上，自己做的程序。帖到这里，希望有人能改进它们，交流经验这样更有价值。 遗传算法解决最小生成树问题，PURFER编码。 粒子群算法做无约束最优化问题。 蚁群算法解决TSP问题。 (matlab genetic algorithm GA, particle swarm optimization PSO, some time ago on the ant colony algorithm intelligent calculation AS experimental course, make their own programs. Posts here, I hope someone can improve their exchange of experience is more valuable. Genetic algorithm to solve minimum spanning tree problem, PURFER code. Particle Swarm do unconstrained optimization problems. Ant colony algorithm to solve TSP problem.)

这是光学激光仿真相关书籍的源代码，里面有全面的关于激光器以及介质仿真的基本代码，这是第二部分的内容，总共有6个部分。(This is the simulation of the optical laser source code related books, which has comprehensive information regarding the lasers and media simulation of the basic code, which is the second part of the content, a total of six sections.)

对H矩阵进行高斯消元，另外附加了高斯消元的论文(The H matrix using the Gauss elimination, an additional Gauss elimination of papers)

对该题目的这篇论文进行了仿真，内容为对比MASSIVE MIMO和Small cell两种模式，比较了载波能量。(The topic of this paper simulation, content and Small cell contrast MASSIVE MIMO modes, compared carrier energy.)

本论文首先介绍了当前深空通信的编码调制技术的现状与发展，阐述了以往 的深空通信中的编码和调制技术的方案和局限性，提出LDPC码和FQPSK调制的 优越性和发展前景。第二章描绘了LDPC码的奇偶校验矩阵的图形表示、生成方 式和译码方法，并比较二元LDPC码和多元LDPC码的优越性和实现问题。第三 章在介绍FQPSK调制的方案的由来、改进和发展的基础上，对其进行了功率谱分 析，介绍了一些常规的解调方案。(This paper introduces the current situation and development of the technology of deep-space communication code modulation on the coding and modulation techniques in deep space communications program and limitations of the proposed of LDPC codes FQPSK modulation superiority and development prospects. Chapter II depicts a graphical representation of the LDPC code of the parity check matrix generation method and decoding method, and compare the superiority of binary LDPC codes and multiple LDPC code and implementation problems. Chapter origin in the introduction FQPSK modulation program, improvement and development on the basis of its power spectrum analysis, conventional demodulation.)

得到一些列的离散数据，用matlab，进行曲线拟合(Get some out of discrete data with matlab, for curve fitting)

降维状态观测器是非常重基于T变换的降维观测器设计方法。要的一类观测器(Reduced-order state observer is very important dimension reduction based on T transform observer design method. To a class of observer)
