一个利用matlab simulink仿真简化通信系统的模型。里面m文件为simulink模块参数设置，适合通信基础浅的人理解通信概念同时上手simulin学习(Matlab simulink simulation using a simplified model of communication system. M files inside simulink module parameters for setting suitable person communication shallow understanding of basic concepts of communication at the same time started studying simulin)

说明：  协同网络中继选择算法 一种是基于门限的最大信噪比选择；另一种是基于门限的最小误码率选择，我们将选择一条最佳的中继链路和源节点到目的节点的直接传输链路在目的端进行最大比合并(Research on relay selection algorithm in cooperative wireless Networks)

这个程序主要是实现QAM的调制和解调的过程。(This procedure is mainly the implementation QAM modulation and demodulation process.)

说明：  这是我的本科毕业论文，使用matlab对信号连续进行仿真(信号连续进行仿真)

条带SAR条件下，对目标进行波数域的成像(For the Strip SAR ,the imaging algorithm undre the wave-number domain )

移动通信中的新技术simo技术信道容量仿真(The new technology of mobile communication simo technology channel capacity simulation )

说明：  在多个特征中选取敏感特征，可以降低特征集的维数，提高分类准确率(Select the sensitive feature in multiple characteristics, can reduce the dimension of feature set, improving the classification accuracy )

approximate solutions of 4th order ODE using the Runge–Kutta method (RK4)

FIR filter for signal

说明：  梯度下降法对数据进行分类，并取了四个数据点，对分类进行证明。对梯度下降法有详细的备注。(The gradient descent method classifies the data and takes four data points to prove the classification. There are detailed remarks on gradient descent method.)
