Iterative decoding of baseband and channel codes in a long-range RFID system

Abstract

In this work we propose an iterative decoder scheme for a long-range RFID system. Based on the results of existing works that suggest it is beneficial to employ forward error correction in future RFID systems, we investigate the possibilities for iteratively decoding the baseband code and the channel code of the system. We evaluate the proposed scheme by simulating its bit-error rate performance and analyze the convergence behavior of the iterative decoder, based on its extrinsic information transfer characteristics.
