Abstract :
In this paper, powerful coding techniques for differential space-time modulation (DSTM) over Rayleigh flat fading channels and noncoherent demodulation without channel state information at the receiver are investigated. In particular, multilevel coding (MLC), bit-interleaved coded modulation (BICM), and so-called hybrid coded modulation (HCM) are devised and compared using capacity arguments. For improved noncoherent reception multiple-symbol differential detection (MSDD) and a low-complexity version of MSDD are adapted to DSTM.
