Outage Analysis of Single-Stage Relay NOMA Over Power Line Communication Under Impulsive Noise

In this paper, we study and present the performance based on the outage probability of a single-stage, relay-aided, cooperative non-orthogonal multiple access over power line communication under a Bernoulli-Gaussian impulsive noise. The network setup comprises one source node and two destination nodes, among which one of the nodes closer to the source acts as a relay, transmitting a symbol from the source node to the destination. The relay considered is a decoded-and-forward relay, which helps to transmit the source symbol to the destination over two-time frames. We derive the mathematical expressions to determine outage probabilities at the relay and destination nodes within the studied network. Furthermore, we develop an optimization problem related to the power distribution coefficient at the source, deriving the corresponding mathematical expressions. To validate our analysis, we employ simulations and numerical methods.
