Abstract :
In a situation where different standard-based wireless PANs/LANs operate sharing the same frequency band in neighboring areas, it is important to suppress interference from/to other networks. This paper proposes a -steering adaptive array antenna to suppress interference for terminals in OFDM-based wireless networks. Taking advantage of the characteristics of OFDM waveform, the array antenna has a simple structure and weight control algorithm. Computer simulation results show that the proposed -steering array antenna can achieve good BER performance and outperforms a beam-steering array antenna in a scattering-rich indoor environment.
