Abstract

Smart antenna has been recognized as a promising technology to improve wireless communications. Interference suppression, power consumption reduction and high data rates support are some of its advantages. Radio frequency identification (RFID) demands power efficiency, better reading ranges, tracking tag signals and interference mitigation. In this paper, a smart antenna processing for RFID systems is implemented. Space Time adaptive processing (STAP) with digital down converters, IQ beamformer and complex least mean square (LMS) algorithm has been designed and validated on Xilinx z7020 field programmable gate array (FPGA) platform. The system exhibits good performance in term of bit error rate (BER) when signal to noise plus interference ratio (SNIR) is over 1 dB with signal to noise ratio (SNR) of 7 dB environments.
