Abstract
NOMA and massive MIMO have both been proposed for achieving SE and EE in 5G wireless networks. However, some studies have considered the combination of both technologies in a single system. Accordingly, this paper investigates the performance of NOMA within massive MIMO for the first time. The analysis adopts a random matrix theory method. The method and considers both the case where the users share the same frequency for transmission purposes and the case where each user can use different frequencies for its transmissions. A new SINR performance measure is proposed. Closed-form expressions for the BER, outage probability and outage capacity are additionally derived.
