在时域中表示，短时傅里叶变换，取1000个采样点，加窗函数，画出原始信号，三维，等高图(In the time domain, said the short-time Fourier transform, take 1000 a sampling point, add window function, draw the original signal, 3 d, contour map)

盖尔圆法进行信号源数估计，方面不错。也可应用于聚类算法。(Source number Gail round signal estimation method, good aspects. Can also be applied clustering algorithm.)

This is a project for Gas agency System.You can check the doc and sourcecode

CLRC663 是高度集成的收发器芯片，用于 13.56 兆赫兹的非接触式通讯。CLRC663 收发器芯片支 持下列操作模式 • 读写模式支持 ISO/IEC 14443A/MIFARE • 读写模式支持 SO/IEC 14443IB • JIS X 6319-4 读写模式支持（等效于FeliCa 1 方案，请参阅章节 21.5） • 相应于 ISO/IEC 18092 的被动发起方模式 • 读写模式支持 ISO/IEC 15693 • 读写模式支持 ICODE EPC UID/EPC OTP • 读写模式支持 ISO/IEC 18000-3 mode 3/ EPC Class-1 HF CLRC663 能够透过内建发射器直接驱动外置天线与 ISO/IEC 14443A 或 MIFARE 卡片进行通信，而无 需附加有源电路。数字模块负责全部的 ISO/IEC 14443A 组帧和错误检测功能（奇偶校验和 CRC 循環 冗餘校驗）(The CLRC663 is a highly integrated transceiver IC for contactless communication at 13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz. The CLRC663 transceiver ICs support the following operating modes • read/write mode supporting ISO/IEC 14443A/MIFARE • read/write mode supporting ISO/IEC 14443B • read/write mode supporting JIS X 6319-4 (comparable with FeliCa 1 (see Section 30.5) scheme) • passive initiator mode according to ISO/IEC 18092 • read/write mode supporting ISO/IEC 15693 • read/write mode supporting ICODE EPC UID/ EPC OTP • read/write mode supporting ISO/IEC 18000-3 Mode 3 The CLRC663’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443A/MIFARE cards and transponders without additional active circuitry. The receiver module )

说明：  齿轮动力学，考虑的因素较多，有位移，法向力。(Gear dynamics, take into account many factors, displacement, normal force.Hopefully it will be useful)
