A QPSK simulation using simulink. very useful to understand the scheme at every level of QPSK modulation.

阵列信号处理方面10个经典程序，包括波束形成，capon，MVCR等等，以及仿真图(10 classic program in array signal processing )

Some New Indexes of Cluster Validity

平面波展开法计算的二维声子晶体带隙，分别是正方与圆形散射体形成正方格子声子晶体，最后输出了能带图的数据，需要自己用画图软件画出来。(Plane wave expansion method to calculate the band gap of two- dimensional phononic crystals, which are square with rounded square lattice formed scattering crystal, the final output of the energy band diagram of the data, so you need to use drawing software drawn.)

smith chart计算，通过阻抗计算，仿真smith chart圆图，帮助仿真。(Smith chart calculation, through the impedance calculation, simulation smith chart round chart to help the simulation.)

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)

主要关于循环码的MATLAB仿真分析源程序及结果图。(Cyclic codes is mainly concerned with the analysis of the source code and MATLAB simulation results Fig.)

本算法可以用于 多因变量和但因变量 的pls 回归(The algorithm can be used for multi-variable and because pls but variable regression)

最优波束形成。最优波束形成器能在干扰方向形成深的零陷。(Optimal beamforming. Optimal beamformer is formed in the depth direction of the interference nulling.)
