给定极化状态的相位描述子和幅度描述子，绘制该极化状态的poincare功率球。源代码是matlab子函数，输入参数两个：极化状态的幅度描述子和相位描述子。还有一张示例图(Given the polarization state of the phase and amplitude descriptors descriptors, to draw the polarization state poincare power ball. Functions matlab source code, two input parameters: the polarization state and phase amplitude descriptor descriptor.)

matlab例子 对于初学者来说很好用，或者用于学习编程 物理 等其他学科，这是一些很好的例子(matlab example)

改进的pso算法（3个m文件和一个说明文件）： 本算法实现Clerc and Kennedy 2002年对pso算法的重要改进-Improved PSO algorithm (Improved PSO algorithm (3 m documents and a note): This algorithm Clerc and Kennedy 2002 years, the importance of improved PSO algorithm )

PCA预测回归的一个例子，简单易懂 也有注释，导入数据注意格式即可使用(An example PCA regression forecasting, easy to understand but also notes, pay attention to the format to use to import data)

全桥逆变器，做的比较好，很清晰。全桥逆变器，做的比较好，很清晰。(Full-bridge inverter, do better, is very clear. Full-bridge inverter, do better, is very clear.)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)

该算法在优化方面性能比较好，可用于函数极值，解方程，并且在前向神经网络权值和网络结构的训练也表现了不错的性能(The algorithm in the optimization performance is better, can be used in extreme value function, solve equations, and the former to the neural network weights and network structure of training has shown good performance)

说明：  对于学习通信原理并且要求运用matlab仿真的学者来说是一本很好的书籍。(Communication Theory for the study and asked the scholars to use matlab simulation is a very good book.)

这是一个很好的学习SIMULINK建模的基础教程，通过该课程的学习可以快速掌握SIMULINK的基本技巧。(This is a good basis for learning SIMULINK modeling tutorial, by the course of the study can quickly grasp the basic skills SIMULINK.)
