calculate and plot M-PSK for AWGN channel with exact phase

自己写的关于方程求根的matlab程序，仅供参考(Roots of equations to write about the matlab program, for reference only)

此程序用来在MATLAB中创建泰森多边形，并且在产生随机中心点的同时，各中心点必须满足特定的距离关系，最后输出中心点坐标以及相应的顶点坐标，以在ABAQUS中建模。(This procedure is used in MATLAB create Thiessen polygons, and at the same time generating random center point, each center must meet specific distance relationship, the final output of the center coordinates and the corresponding coordinates of the vertices to model in ABAQUS in.)

说明：  产生四部雷达信号，并对其进行分选，包括抖动，参差等信号(Four radar signals are generated and sorted)

本函数将完成W—svd模型下数字水印的嵌入，即经典的W-SVD数字水印算法(This function will finish W- SVD model under the embedded watermark, namely classic W- SVD watermarking algorithm is proposed)

说明：  对信道的仿真，采用QPSK调制，分别在瑞利和高斯信道条件下，也包括CRC较验(Simulation of the channel, using QPSK modulation, respectively, Rayleigh and AWGN channel conditions, but also more experience CRC)
