说明：  QPSK仿真，通过高斯信道，瑞利信道进行调制解调，计算误码率，绘制星座图(QPSK simulation, through the Gaussian channel, Rayleigh channel modulation and demodulation, calculate the bit error rate, draw constellation)

本章将涉及比较深层的 MATLAB 内容：脚本；函数（一般函数、内联函数、子函数、 私用函数、方法函数）；程序调试和剖析；数据结构（类、对象）；重载和继承；面向对象 编程。本章配备了许多精心设计的算例。这些算例是完整的，可直接演练的。读者通过这些 算例，将真切感受到抽象概念的内涵、各指令间的协调，将从感知上领悟到面向对象编程的 优越和至关要领。(MATLAB )
