Description: 这个例子将产生并显示pi/2 DQFSK系统中的一些重要信号，仿真这个系统并产生图形输出的MATLAB程序在文件夹中给出。在MATLAB的命令提示符下输入程序名c8-pi4derno后，会绷现一个菜单，用户可通过这个菜单选择以下七个选项中的一个（产生一个图形后，击空格键会显示菜单以便作另一个选择）
1.滤波前的pi/4 DQPSK信号星座图
2.滤波前的pi/4 DQPSK眼图-
3.滤波后的pi/4 DQPSK信号星座图
4.滤波后的pi/4 DQPSK眼图
5.滤波前的同相和正交信号
6.滤波后的同相和正交信号
7.退出程序(返回MATLAB命令提示符)
读者应该仔细研究文件夹中的内容，因为它阐明了很多常见的后处理过程，而且，产生各种图形的代码可用于其他仿真程序的后处理器。
