Cyclic Delay Diversity (CDD) exploits the principle of the Orthogonal Frequency Division Multiplexing (OFDM) that transforms the delay spread into the frequency selectivity. In order to investigate the performance of the CDD, OFDM in combination with bit-interleaved coded Differential Phase Shift Keying (DPSK) is theoretically analyzed in terms of Pairwise Error Probability (PEP). Recently, classical delay diversity techniques have regained attraction for their simple structures and superior performance. Delay diversity can be implemented by transmitting delayed replicas of a signal from several antennas. A combination of delay diversity and Orthogonal Frequency Division Multiplexing (OFDM) may be an attractive candidate for next-generation high data rate communications.
