Two-User Network-Coded Cooperation With NOMA and Advanced Successive Interference Cancellation

In this work, we evaluate the outage probability of a two-user network-coded cooperative (NCC) uplink system subjected to non-orthogonal multiple access (NOMA). We consider that the destination performs a recently proposed advanced successive interference cancellation (Adv-SIC) in order to decode the individual messages from the superimposed received signal, which requires only statistical channel state information (CSI). Our results indicate, through mathematical analysis and numerical simulations, that the benefits of Adv-SIC are boosted by NCC, improving the performance of both users, differently from a non-cooperative (NonCooP) NOMA system, where only the user with the worst average channel condition is benefited from Adv-SIC.
