AB  - In this paper, we propose a non-orthogonal multiple access (NOMA) relaying 
      system, where a source node communicates simultaneously with multiple users via 
      the assistance of the best amplify-and-forward (AF) relay. The best relay is 
      selected among N relays which are capable of harvesting the energy from radio 
      frequency (RF) signals. We analyze the performance of the proposed NOMA relaying 
      system in the conditions of imperfect channel state information (CSI) and 
      Rayleigh fading by deriving the exact expressions of the outage probability (OP) 
      and the approximate expression of the ergodic capacities of each user and the 
      whole system. We also determine the optimal energy harvesting duration which 
      minimizes the OP. Numerical results show that, for the same parameter settings, 
      the performance of the proposed NOMA relaying system, especially the ergodic 
      capacity of the whole system, outperforms that of the orthogonal-multiple-access 
      (OMA) relaying system. Monte-Carlo simulations are used to validate the 
      correctness of the analytical results.
