This paper investigates the fundamental performance limits of downlink power-domain non-orthogonal multiple access network in the presence of co-channel interference. The investigation considers that base-station makes multiple information exchanges with a designated mobile terminal via the power-domain non-orthogonal multiple access technique. The investigation also considers that the designated mobile terminal is under the effect of a limited number of co-channel interference, which are independent and identical distributed random variables subject to Rayleigh fading. Analytical, asymptotic, and Monte-Carlo based intensive computer simulation results reveal that co-channel interference causes coding gain losses on free-interference case, utilized as a benchmark, in high signal-to-noise-ratios. Outage probability, error probability, ergodic rate, and throughput performance metrics are considered for the performance analysis. Optimization techniques and also asymptotic analysis are provided.
