Abstract

Considers an OFDM system with cochannel interference and the use of adaptive antenna arrays to suppress such interference. Based on the conventional RLS criterion, we derive a new recursive least square (RLS) adaptive beamforming algorithm for antenna arrays applied in an OFDM system. Computer simulation shows that when applied to the OFDM system, the proposed algorithm is capable of combating cochannel interference in both AWGN channel and multipath Rayleigh fading channel with AWGN.
