QPSK在AWGN下的仿真

说明：  Dynamic and steady state model of Doubly fed induction generator back to back supply for wind energy power system using matlab

this coding use for students who use matlab steganography. the code will be highly used in recent times.

说明：  输入在某一平面中的点云数据构成的原始nx3矩阵，拟合出该平面(The original NX3 matrix formed by inputting point cloud data in a plane is fitted to the plane.)

本程序为标准微粒群算法的画图源码，该源码可以画出各种优化图形，描述优化过程(This procedure as the standard particle swarm algorithm for drawing source, the source can be optimized to draw a variety of graphics, optimization process described)

经验模态分解程序集，一类可以有效进行信号分段以及分析和处理的源代码。(Empirical mode decomposition procedure)

实用的IGBT的RCD吸收电路，采用真实器件参数，做到基本无尖峰且吸收能量最小，保持开关管最小应力！！(Practical IGBT of RCD snubber circuit, using the real device parameters, so that almost no energy absorption peak and minimum, keep the switch minimum stress! !)

运用fdtd算法研究2维介质圆柱散射的程序(The use of the fdtd Algorithm for 2-D dielectric cylinder scattering process)

模式识别中训练决策树、测试决策树、计算决策树中熵不纯度的函数。(Pattern recognition training decision tree, test tree, tree entropy calculation is not a function of purity.)

线性卷积和循环卷积的matlab生成，源程序为此(Linear convolution and circular convolution matlab generate, source code)

These are digital modulation source codes.
