摘要：
In this paper, we investigate a Raptor-coded distributed noncoherent scheme based on a non-orthogonal space-time modulation (NOSTM) signal and a dynamic decode-and-forward (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 of the NOSTM signal. A Raptor-coded distributed scheme is then constructed for the relay network, and the corresponding transmission and reception procedures are also investigated. It is shown that the throughput performance can be effectively improved, especially for cases when the location of the chosen relay nodes is distant from the source node.
