本实验利用蒙特卡洛分析方法，通过MATLAB仿真了QPSK,16QAM基带传输系统AWGN和Rayleigh信道下的系统BER性能。仿真过程中通过，m文件的编写，将两个基带系统仿真的结果画在了一张图上(In this experiment, the BER performance of QPSK, 16QAM baseband transmission systems in AWGN and Rayleigh channels is simulated by using Monte Carlo analysis method and MATLAB. In the process of simulation, the simulation results of two baseband systems are drawn on a graph by compiling m files.)

发现usb_hid网上可参考的资源少，基于C#源码的就更少了，尤其是能通过验证的资源简直是没有，本usb hid源码在两三个银行用外部标准接口的硬件设备（如柜外清，条码识别，及指纹识别）测试通过了，关键是已经封装成了一个C#控件，使用时只需调用UsbLibrary.dll文件就行了，别再用那writefile了(Found usb_hid fewer resources available online reference, based on C# source code and even less, especially through the resources simply do not verify the source usb hid in two or three banks with an external standard hardware interfaces (such as outside the cabinet cleared , barcode recognition, and fingerprint recognition) test, the key is already packaged into a C# controls, just call UsbLibrary.dll file when using the line, do not use that writefile the)
