Abstract
For the UHF EPC C1 Gen2 RFID system, to overcome the performance degradation in wireless channel environments, we proposed a modified tag structure which supports channel coding and its applied methodology. The reader consistently monitors the wireless channel status and sets to use channel coding functions for tags and reader only if wireless channel is corrupted. Compared with previous tag complexity, only negligible gates are needed to implement channel coding. By simulation we showed an obvious performance improvement of the identification reliability.
