This program plots the BER vs SNR for a 4X4 MIMO-OFDM system.

MATLAB自己做的 好像有点问题 希望朋友们帮忙解决一下(matlab)

Clarke模型的提出代表了Rayleigh分布用于平坦小尺度衰落统计模型的开端。虽然因为其实现比较复杂，而更倾向于被认为是一种数学模型而非仿真模型，但所涉及到的Rayleigh衰落信道的概念是其后众多改进模型的基础(The Clarke model put forward on behalf of the beginning of the Rayleigh distribution for flat small-scale fading statistical model. Because its implementation is more complex, and more inclined to think that instead of the simulation model is a mathematical model, but involved in the Rayleigh fading channel concept is the basis of many subsequent improvement model)

设计特定的进化操作或约束修正因子。文献[ 28 ]采用罚函数法,利用非固定多段映射罚函数对约束优化问题进行转化,再利用PSO求解转化后的问题,仿真结果显示PSO相对进化策略和遗传算法有优越性,但其罚函数的设计过于复杂,不利于求解(Operation or design of the evolution of specific binding correction factor. Literature [28] The penalty function method, using non-stationary multi-stage fine mapping function to transform constrained optimization problem, and then transformed using PSO to solve the problem, simulation results show that PSO is relatively evolution strategy and genetic algorithm has advantages, but the penalty function The design is too complex and not conducive to solving)

说明：  真对无线通信中的正交频分复用的matlab仿真源代码。(True for wireless communications in orthogonal frequency division multiplexing matlab simulation source code.)

数值积分和数值微分的相应方法，程序测试无误。(Numerical integration and numerical differentiation of the corresponding program to test and correct. )

通过MATLAB仿真来讨论比较二元霍夫曼编码、三元霍夫曼编码以及信源扩展编码的效率，来实现霍夫曼码的优化构造(By MATLAB simulation to compare two yuan Huffman discussed, ternary Huffman coding and source coding efficiency extended to achieve optimization of Hoffman Construction Code)

根据ANSYS分析得到位移时间数据点后，可用MATLAB拟合其衰减曲线(ANSYS analysis based on data obtained after displacement time point, the attenuation curve fitting is available MATLAB)

说明：  it is a very good way to use matlab simulink for analysis of control systems in nature
