Zusammenfassung:The DAPSK-MC-CDMA scheme is proposed and the sensitivity of carrier offset and MAI are investigated in this paper. Comparisons of differential and coherent modulations under different detection algorithms have been performed. Simulation results show that the proposed scheme is superior to traditional coherent schemes in reducing the effect of MAI and carrier frequency offset.
