Hybrid Protocols for Relay-Assisted Non-Orthogonal Multiple Access in Power Line Communications

We study the outage probability performance of hybrid protocols in relay-assisted, non-orthogonal multiple access (NOMA)-based power line communication. In particular, we consider two networks with source, relay and destination nodes, namely, cooperative relaying NOMA (CR NOMA) single-stage (SS NOMA). derive closed-form expressions for probabilities three techniques, decode-and amplify-and-forward (HDAF), incremental HDAF (IHADF) IHDAF maximal ratio combining (MRC) protocols. The protocol overcomes limitations decode-and-forward (DF) (AF) protocols, by advantages both. protocol, advantage successful decoding at receiver is exploited using direct link between source added benefit due to HDAF. Through an extensive simulation study, (a) validate our analysis, (b) show that IHDAF-MRC outperforms IHDAF, HDAF, DF AF, (c) CR SS when scheme employed.
