Capacity and Outage Probability Analysis of Faster-Than-Nyquist Cooperative NOMA

This letter proposes a novel cooperative non-orthogonal multiple access (C-NOMA) based on precoded faster-than-Nyquist (FTN) signaling. The additional gain in degrees of freedom obtained from FTN signaling is exploited the context relaying-induced diversity inherent to C-NOMA. We derive achievable ergodic rate proposed scheme while also deriving closed-form expression scheme’s outage probability, which shows improved fairness far user. Our simulation results substantiate advantages over conventional benchmark methods.
