bpsk
代码经过bpsk调制，经过AWGN高斯白噪声信道加噪后，在经过硬判决和bpsk解调后，经解调后的码和初始码元进行对比，计算得出错误码元数量，错误码元数量除以总的码元数量得出误码率，在不同的信噪比情况下得到不同信噪比条件下误码率曲线

脉冲激光测距中高精度时间间隔系统设计_田海军
脉冲激光测距系统工作原理即单片机控制激光发 射装置发射占空比一定的激光脉冲，其中一小部分能量 到达接收电路，然后光电探测器将微弱的光脉冲信号变 成电脉冲信号并看作Start信号触发时差测量。激光的 大部分能量在空间中传播，遇到目标物后反射传播到 达接收电路，看作Stop信号结束测量，至此完成时差测 量[2]。TDC?GP22芯片记录Start脉冲到Stop脉冲之间的 时差，用于计算目标物到发射端的距离。(The principle of the pulse laser range finding system is that the single-chip microcomputer controlled laser emission device launches a certain laser pulse, in which a small portion of the energy reaches the receiving circuit, and the photodetector turns the weak light pulse signal into the electric pulse signal and is considered as the time difference measurement of the trigger time of the Start signal. Most of the energy of the laser propagates in the space. After the target, the reflection transmission reaches the receiving circuit, which is regarded as the end of the Stop signal and then completes the time difference measurement [2]. The TDC GP22 chip records the time difference between Start pulse and Stop pulse, which is used to calculate the distance between the target and the transmitter.)

MFCWindows12
MFC Windows程序设计(第二版)中文版
很多人说孙鑫或者vc++技术内幕很经典，但是我要说这本书才是（我认为）学习mfc最经典的教材。至于深入浅出mfc太注重底层细节技术，就像看电视知道怎么开就行，不需要知道太多集成电路板的原理。
另外学习mfc还有没有必要，我觉得有个承上启下的作用，很多mfc编写的大量源代码可以参考，自己重新写可能有点费劲。新的.net平台也支持,并且有了c++基础学习C#其实也很快。
可以单独下载，单独解压。看着觉得合适再下载其他部分。(MFC Windows Programming (second edition) A lot of people say the Chinese version of SUN Xin or vc technology is a classic insider, but I have to say this book is (I think) mfc learning materials and classic. As easy mfc too focused on the bottom of the details of technology, like watching television know how to open on the line, do not need to know that too many of the principles of integrated circuit board. In addition there is no need to learn mfc there, I think there is a role of connecting many mfc prepared a large number of source code can refer to his own re-write may be a bit strenuous. New. Net platform also supports, and with c -based learning is also soon CSharp. Available as a separate download, a separate decompression. Looking at the right feel)
