Abstract
This paper proposes a novel blind channel estimation method for STC-OFDM with two transmit antennas and one receive antenna. The number of received blocks needed for blind channel estimation is significantly reduced by repeated use of the same blocks. This feature makes it more realistic when the channel state is fast-varying. Simulation results confirm that the proposed method is effective.
