Abstract(in English) | UHF-band active RFID (radio frequency identification) systems need to communicate each other correctly under existence of a frequency offset up to 40-kHz between a reader and a tag, because the frequency tolerance to the specified low power radio station in 950 MHz-band is 20-ppm. This frequency offset degrades eye openings of the transceiver largely. Therefore, the BER (bit error rate) between the reader and the tag increases. In a practical use, the frequency offset have to be compensated under large adjacent channel interference. This paper proposes an effective method to compensate the frequency offset using a numerical PLL. This enables us to detect offset frequency accurately under the adjacent channel interference which SIR (signal to interference ratio) is 0 dB. |
