Abstract: In this paper, a hybrid full duplex (FD) and half duplex user relaying cooperative non orthogonal multiple access (NOMA) system is investigated which addresses the ergodic capacity problems with successive interference cancellation (SIC) technique. The residual self interference (RSI) exists due to imperfect self-interference cancellation. An advanced successive interference cancellation (ASIC) technique is introduced in the system to resolve the issues of unnecessary user decoding delay due to iterative decoding nature of SIC. The proposed scheme is implemented by mapping the received signal into number of subgroups. Then, the desired information signals are obtained by applying conventional SIC technique to each of these subgroups. The proposed system is characterized by deriving the closed form analytical expressions of ergodic capacities for NOMA users, energy efficiency and ergodic sum capacity under RSI. The analytical results are presented to show the effectiveness of the proposed system with ASIC over traditional system with SIC in terms of ergodic capacities for NOMA users, energy efficiency and ergodic sum capacity. Moreover, the energy efficiency and ergodic sum capacity of the proposed system also make it better than ASIC based FD NOMA system with dedicated relaying under same conditions.
