一个QPSK的simulink模型，希望对大家有用，谢谢(The simulink model of a PLL, we want to be useful, thank you)

二维FDTD程序，采用PML边界s 用pml和mur分别计算j=1处的Hz(i,1).计算空间扩大到400*400，不加边界，运行相同的时间步(2D FDTD procedures, Application of the PML's border with pml and mur calculated j = 1 Hz of (i, 1). for the space to expand to 400* 400, without borders, running the same time step)

移相键控（PSK）中的二相移相键控（2PSK）算法，建立了MATLAB文件。(Phase shift keying (PSK) in the two-phase phase-shift keying (2PSK) algorithm, the establishment of the MATLAB file.)

基于matlab的智能交通系统 可以进行运动车辆的检索和追踪(Intelligent transportation system based on matlab can search and track moving vehicles)

实现了zf和MMSE预编码下的信道容量，对朋友们的学习会有一定的帮助(ZF and MMSE precoding channel capacity, with the help of some friends learning will be )

可以用来演示傅里叶级数 逐项累加 逼近矩形波的效果(Can be used to demonstrate Fourier series, item by item, accumulative approximation of the rectangular wave effect)

AR模型参数确定后计算出功率谱, 用Levision_Durbin 算法(AR model parameters were calculated to determine the power spectrum, using Levision_Durbin algorithm)

PID解耦，用于多变量解耦，是个很好的例子，希望对大家有用(PID decoupling, for multi-variable decoupling is a good example, in the hope it would be useful)
