|Title:||Distributed Spatial Modulation Aided NOMA||Authors:||Shehni, Amir; Flanagan, Mark F.||Permanent link:||http://hdl.handle.net/10197/11136||Date:||21-Jun-2019||Online since:||2019-10-09T16:45:10Z||Abstract:||In this paper, a novel cooperative diversity protocol based on the association of non-orthogonal multiple access (NOMA) and distributed spatial modulation (DSM) is introduced. In the proposed protocol, two source symbols are multiplexed in the power domain, while one source symbol obtains a diversity gain due to its being relayed according to the DSM principle; this doubles the data rate for the source-to-destination link as compared with conventional DSM. We propose two demodulators for use at the destination: an error-aware demodulator which is robust to demodulation errors at the relays, and a suboptimal demodulator which assumes error-free demodulation at the relays. Simulation results demonstrate that while the proposed protocol achieves a source data throughput equal to that of a full-duplex system, its BER performance also significantly outperforms the full-duplex relaying benchmarks of successive relaying and virtual full-duplex DSM.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2019 IEEE||Keywords:||Cooperative communication; Demodulation; Diversity reception; Multi-access systems; Protocols; Relay networks; Telecommunication||DOI:||10.1109/eucnc.2019.8801970||Language:||en||Status of Item:||Peer reviewed||Is part of:||2019 European Conference on Networks and Communications (EuCNC)||Conference Details:||The 2019 European Conference on Networks and Communication (EuCNC), Valenica, Spain, 18-21 June 2019||ISBN:||978-1-7281-0546-8|
