mysim_4ask.m
simulation of 4 ask
this simulation need more improvement.
I ll refine it later but it has the basic for a 4ask signalling scheme.
it ll compare the result with analytical answer and depicts it in a semilog plot.

了一些资料，都没有说这个仿真平台是什么，是matlab还是直接在VC++的编译环境编程？还是有专门的仿真环境呢？
3、如果用实物验证的话，我觉得有两种方式：一是用摄像头来采集整个地图信息，智能车的位置也有摄像头来反馈；二是，整个地图保存在内存中，小车根据传感器信息自我定位，然后和保存的地图比较。(You can download the current points to 1, the source download get points one day, you can download up to 20 times.
