仿真QPSK信号通过瑞利衰落信道的误比特率，并与AWGN信道下误比特率进行比对(Simulation of QPSK signal through the Rayleigh fading channel bit error rate, and AWGN channel bit error rate comparison)

此源码是我更改过的基于VFW(Video for Windows)的源码，使用了定时器能实时的显示图像，从网上可搜到原版源码，但是原版的功能是保存为一个文件，且不能实时显示，此版本虽然能显示，但感觉反应速度不是很快，没有基于DirectShow的程序更新速度快，不过在WM_PAINT消息处理里加while(1){capGrabFrame(ghWndCap) }刷新速度就快很多了，但是这样程序就进入死循环不能再处理其他消息，至于怎样改进，就靠读者你了。(This source is changed based on VFW (Video for Windows) source, using a timer to display real-time images from the Internet can be found to the original source, but original function is saved as a file, and can not be real-time display, Although this version can display, but feel the reaction rate is not fast, not based on DirectShow update speed, but in WM_PAINT message processing Riga while (1) {capGrabFrame (ghWndCap) } faster refresh rate on a lot, but this procedure to enter an infinite loop can not deal with other information, as to how to improve the reader to rely on you.)
