In this paper, we investigate a Raptor-coded distributed noncoherent scheme based on a non-orthogonal spacetime modulation (NOSTM) signal and a dynamic decode-andforward (DF) relaying scenario. The distributed NOSTM signal is firstly proposed based on unitary space-time modulation (USTM) and spatial multiplexing (SM). The dynamic DF relaying protocol is investigated to process the non-orthogonal feature...
In this paper, we investigate Raptor-coded distributed unitary space–time modulation (USTM) schemes, where both the amplify-and-forward (AF) and decode-and-forward (DF) relaying scenarios are considered, under a wireless relay network with arbitrary path gains for the channel fading coefficients. First, the AF and DF relaying procedures are investigated based on the use of an inner USTM signal and...
