通信系统中信号调制技术，采用8PSK对信号进行调制的matlab仿真。(Communication system signal modulation technology, the signal 8PSK modulation matlab simulation.)

简易四则运算计算器，使用时需将.m和.fig文件放到matlab工作目录下（本人使用的是R2013，放到bin文件夹即可，其他版本放到对应文件夹，有的是work文件夹），然后在命令窗口输入.m文件的文件名，即可显示一个简易计算器界面。有0-9九个数字供点击输入数，有重置和正负号按钮，界面简洁，功能耐用(Simple arithmetic calculator should be used with the. M and. Fig file into matlab working directory (I use the R2013, into the bin folder to the other versions into the corresponding folder, some work folder) , and then in the command window. filenames m file to display a simple calculator interface. 0-9 nine figures for the number of click enter, and the sign has reset button, the interface is simple, functional and durable)
