Performance Analysis of NOMA Over n-m Fading Channels with imperfect SIC

In this paper, a downlink non-orthogonal multiple access (NOMA) network with two users is considered. particular, the performance of NOMA evaluated by assuming perfect and imperfect channel state information (CSI). We derive closed-form expressions for outage probability over η − µ fading channels in special case users. Moreover, proposed system model-based always achieves better than that CSI medium SNR region. Monte Carlo simulations are then performed to confirm good match analytical results.
