    Abstract
    This paper analyzes the characteristics of four kinds of possible channels in UHF RFID communication system, and makes a deep analysis on additive white Gaussian noise channel and binary symmetric channel. At the same time, it sets up the ASK modulation and demodulation simulation models of those two kinds of channels, summarizing the relationship between the bit error rate and the variety of signal to noise ratio of those two kinds of system. Finally, it concludes the optimal parameter of transmission process in the RFID system in experiments.
