Aspects of data reception in a high performance RFID reader

Abstract

A new RFID reader for the 13.56 MHz carrier frequency was developed in the framework of the collaboration between Freaquent Frosch Electronics (FE) and the first author. The reader is intended to cover the standards ISO/IEC FDIS 18000 [1], ISO/IEC FCD 15693 [2] and to provide long-range reading as well as inventory of large collections of tags. The reader features a class E switching power amplifier in the transmission path and several means for achieving a high quality signal in the reception path. Our paper will be focused on the procedures we developed for processing, storing and decoding the signal received from tags.
