8QAM
利用Matlab仿真软件,完成如图1所示的一个基本的数字通信系统。信号源产生0、1等概分布的随机信号,映射到16QAM的星座图上,同时一路信号已经被分成了实部和虚部,后边的处理建立在这两路信号的基础上。实部、虚部信号分别经过平方根升余弦滤波器,再加入高斯白噪声,然后通过匹配滤波器(平方根升余弦滤波器)。最后经过采样,判决,得到0、1信号,同原信号进行比较,给出16QAM数字系统的误码。(Using Matlab simulation software, as shown in Figure 1 to complete a basic digital communications systems. Signal source such as arise over the distribution of 0,1 random signal, is mapped to 16QAM constellation diagram, at the same time all the way the signal has been divided into real and imaginary parts, behind the deal with the establishment of these two signals in the basis. Real part, imaginary part of the signal, respectively, after a square root raised cosine filter, then add white Gaussian noise, and then through the matched filter (square root raised cosine filter). Finally, after sampling, the verdict has been 0,1 signal, to compare with the original signal is given 16QAM digital system error.)

1. 该光盘包含了“信号与系统分析及MATLAB实现”一书的第七章所有程序;
2. 为了方便读者阅读程序,所有程序均采用中文注释。MATLAB的程序编辑器不支持中文显示,用户只需在Word下直接打开源程序文件,即可阅读程序中的中文注释;
3. 程序文件的命名分为以下三种类型:
(1) 若为书中例题的程序,则程序文件名一律以ex开头,后面跟4位数字(前两位表示章号,后两位表示例题序号)表示的该程序所在例题的编号。例如,ex0603.m是例6.3的程序,而ex1102.m则是例11.2的对应程序。
(2) 若为书中图形的实现程序,则程序文件名一律以figure开头,后面跟4位数字(前两位表示章号,后两位表示图形序号)表示的该程序所绘图形的编号。例如,figure1203.m是实现图12.3的程序,而figure0710.m则是实现图7.10的对应程序。
(3) 若为函数文件,则直接以函数名命名,例如文件sconv.m即是书中函数sconv()的对应程序。
