QPSK modulation in matlab

说明：  雷达目标跟踪中的直观法航迹起始程序，其中包含两个文件：simutrack.m和main.m。simutrack.m是目标轨迹仿真；main.m是主文件。(matlab code for track initialization in radar target tracking.)

偏微分方程的求解，泊松方程的求解，一边大家学习交流(Partial differential equation, the solution of the Poisson equation, while we study the exchange)

利用保留交叉验证(hold-out)的特征选择，有筛选排序的功能，并最终可以输出对应特征下标。(The use of cross-validation reserved (hold-out) feature selection, there is sort of filtering function, and eventually you can output the corresponding feature subscript.)

说明：  MATLAB模块详细介绍，详细介绍了MATLAB的模块，工具箱，Simlink模块(MATLAB module details, details of the MATLAB module, toolkit, Simlink module)

afqrrls算法2，大家多多支持，多多交流(afqrrls Algorithm 2, a lot of U.S. support, more exchanges)

这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )

说明：  利用AR模型仿真瑞利衰落信道，可用为信道建模做参考(Program to simulate Rayleigh fading using a p-th order autoregressive model AR(p) )

一段关于捷联惯导系统的圆锥误差Matlab仿真程序，(Paragraph on the cone error of SINS Matlab simulation program,)

直线插补，主要实现从一点到另一点走直线，用插补的方式来逼近理想直线，尽量减小误差(Linear interpolation, the main achievement one point to another straight line, with the interpolation way to approach the ideal line, to minimize the error)
