A blind channel identification problem based on exploiting the virtual carrier is investigated for MIMO-OFDM systems. Sufficient identifiability conditions are established for MIMO-OFDM channel to be identifiable up to a unitary matrix. And the subspace blind channel identification method is proposed. The method is attractive for its potential to increase the system's channel utilization due to no restriction on length of the cyclic prefix. Computer simulation results are finally provided to… CONTINUE READING
