Abstract :
Multicarrier delay diversity modulation (MDDM) is a scheme that uses orthogonal frequency division multiplexing (OFDM) on a "multipath" channel that is generated by using delay diversity. The full diversity criterion for MDDM is proven and illustrative examples of full-diversity codes are obtained based on the established criterion. Coding gains and interleaver designs are also considered and analyzed. Simulation results for MDDM on quasistatic flat and frequency-selective fading channels are discussed. MDDM is established as a strong competitive technique to existing STBC and STTC techniques for MIMO systems.
