Abstract
For efficient resource utilization, we adopt an efficiency measure, namely the received signal-to-interference-plus-noise ratio (SINR) per unit power for a full duplex (FD) multiuser communications system employing non-orthogonal multiple access (NoMA) transmission scheme. Accordingly, we formulate an optimization problem for a FD NoMA system to maximize the power-normalized SINR (PN-SINR), which involves two stages: 1) smart power allocation to suppress the residual self-interference and 2) smart user clustering through game theory at a stage prior to the power allocation phase to mitigate the co-channel interference. Based on the suppression level of self-interference and co-channel interference, numerical results demonstrate the superiority of FD NoMA over other schemes.
