Abstract
This paper proposes a statistical subspace algorithm for blind channel estimation in OFDM systems. The algorithm is based on a new input/output relationship which is obtained by a matrix transform on the transmission equation of the OFDM systems. The proposed algorithm is computationally simpler, and extends some results of the existing subspace algorithm. The simulation results are also presented.
