Abstract

We proposes a blind equalization algorithm that enables spatio-temporal diversity in OFDM systems. The proposed algorithm is based on the least-squares approach, which exploits the OFDM signal structure and multiple outputs of an antenna array. The sensitivity of the proposed equalizer to the input signal and noise are presented, and the proposed algorithm is evaluated in simulation results
