We propose an improved transmit diversity using space-time block coding for OFDM systems in frequency selective fading channels. With only two transmit antennas, the proposed scheme can achieve a fourth-order diversity in. gain at low complexity. Simulation results for the proposed scheme show that this joint exploitation of spatial diversity and frequency diversity remarkably improves the BER performance.
