Abstract
In this paper, we introduce new full-diversity space-frequency block codes (SFBCs) based on orthogonal space-time block codes (OSTBCs). We show that the proposed schemes are capable of attaining full-diversity and rate-one characteristics for two transmit antennas, although the proof of full-diversity property is limited to the real constellations. Also for the QPSK constellation, we present evidences through simulations that demonstrate the full-diversity property of the proposed SFBCs. The proposed SFBCs also benefit from the maximum coding advantage when partial channel state information is available at the transmitter. Simulation results confirm the performance superiority of the proposed codes over other recently proposed SFBCs under the same complexity at the receiver side.
