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。 (It is very difficult to describe the MATLAB procedure in english.)

说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)

这是matlab的一个教程，比较实用，易于学习。(This is a tutorial matlab, more practical, easy to learn.)

im2html produces HTML text containing a table that displays the image pixel colors and values. When called with no output argument, im2html displays the HTML in the MATLAB Web Browser. When called with an output argument, im2html returns the HTML text as a string. This form can be useful when publishing a MATLAB file.

本程序运用PAST算法估计信号的子空间，MUSIC算法估计波达方向，实现了对信号的入射角度的实时跟踪。(The procedures used PAST algorithm estimates the signal subspace, the MUSIC algorithm to estimate DOA, real-time tracking of the incident angle of the signal.)
