Abstract

Exploiting the effect of frequency diversity based on the frequency-domain channel correlation of OFDM systems, we propose an improved space-time block coding with frequency diversity for OFDM systems in frequency selective fading channels. With only two transmit antennas, the proposed scheme can achieve a fourth-order diversity gain at low complexity. Simulation results for the proposed scheme demonstrate that this joint exploitation of spatial diversity and frequency diversity leads to a remarkable improvement in BER performance.
