c#，指纹仪通信，采集不同指纹，实现一个小型的身份鉴别系统。-c#, fingerprint device communication, samples from the different fingerprints, to achieve a small identification system.

usb识别，可以鉴别所以USB设备，通过PID，VID-the usb connection。

2PSK，QPSK，MSK，QAM的调制方式鉴别，其中有符号速率的估计，频偏的估计，确定载频，并画出星座图，用simulink编写-2PSK, QPSK, MSK, QAM modulation scheme identification, including the estimated symbol rate, frequency offset estimate to determine the carrier frequency, and draw the constellations, w
