Research on the Coding and Decoding Technology in ISO/IEC 14443 TYPEA of RFID

Abstract:

In order to solve the problems of lack of design flexibility, not easy to self-development and involving the intellectual property rights, when adopting special RFID chips in the design of ultra-high frequency radio frequency readers, in this paper, based on analysis of the communication signal interface of protocol ISO/IEC 14443 TYPE A, a trial-and-error method for realization of sending the data with Modified Miller code is put forward, and a new decoding method for Manchester is designed, by combining a RFID analog front end(AFE), the RFID reader can be easily developed. Test results present that the coding and decoding methods can well meet the requirements of ISO/IEC 14443 TYPE A, with high efficiency, stability and accuracy rate.
