【Abstract】 The hardware and software designs of a base band module for Radio frequency identification (RFID) system are described in this paper. This system uses TMS320F2812 as CPU and works on ultrahigh frequency(UHF) . The signal encoding , decoding and anti-collision technique in multiple tags identification are discussed. This system works efficiently and stably in the testing environment.更多还原
