匹配滤波器的实现。主要是通过fft变化使输出自相关最大，在通过滤波器。(Matched filter implementation. Mainly through changes in the output autocorrelation fft the largest through the filter.)

杨建国老师的通讯原理课件，第三章模拟信号的调制与解调，主要讲述信号产生与调制，射频特性，解调，MSK、GMSK、PSK、QPSK、BPSK、QAM等原理(Yang Jianguo teacher communication principles of courseware, the third chapter of the analog signal modulation and demodulation, and focuses on the signal generation and modulation, the RF characteristics, demodulation, MSK, GMSK, PSK, QPSK, as BPSK, QAM and other principles of)

WINDOWS 应用程序（嵌入web浏览器），通过IC/NFC读卡器读取卡号,(IC/NFC card reader,can recognize card sn.)

matlab实现的fft程序，可酌情作为参考(Matlab implementation of the FFT program, as appropriate, as a reference)

产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)

this is a paper for pcf beam splitter!

对数字信号进行相位幅度调制，并在接收端成功解调(QAM of Digital Signal and Successful Demodulation at Receiver)
