Abstract :
In this paper, differential modulation diversity (DMD) is introduced. This diversity scheme is based on diagonal signal constellations which have been previously proposed for differential space-time modulation (DSTM). DMD can exploit both space and time diversity and DSTM, which is a pure space diversity scheme, results as a special case. A low-complexity noncoherent receiver originally designed for DSTM is adapted to DMD and the power efficiency of DMD for spatially correlated Rayleigh fading and imperfect interleaving is investigated
