摘要：
Space-time codes increase the transmission rate of a communication system in fading channels significantly. The decoding of space-time codes generally depends on perfect channel estimation. Differential space-time modulation (DSTM) can work, in a noncoherent manner, over continuously fading channels. However, it exhibits an irreducible error floor in time-correlated fading channels. In this paper, the impact of correlated Rayleigh fading on DSTM is investigated, and a decision-feedback linear prediction receiver for DSTM is presented. Computer simulations show that the linear prediction receiver reduces the error floor substantially.
