Making use of the information redundancy introduced by the cyclic prefix (CP), a new deterministic subspace algorithm for blind channel estimation in OFDM systems is proposed. Considered that only few received signals are used to estimate channel, the algorithm is appealing for transmissions over slowly varying channels. The performances of the proposed algorithm are demonstrated by simulation results
