Abstract
Non-orthogonal multiple access (NOMA) is a major technique that is expected to lead towards the fifth generation (5G) wireless communication networks, as it involves the sharing of space resources among users in a given scenario. In this paper, we propose an uplink (UL) NOMA setup that utilizes the multiple-input multiple-output (MIMO) infrastructure. As performed in related literature, K clients are placed in 'weak' and 'strong' categories, depending on the channel state information (CSI). The base station (BS) uses successive interference cancellation (SIC) to overcome interference experienced by users forming the weak set from their counterparts in the strong set. The paper goes on to compare the performance of this NOMA system with that of a conventional orthogonal multiple access (OMA) setting, with the scope being extended to include both ultra high frequency (UHF) and millimeter wave (mmWave) networks. The performance evaluation is carried out in terms of, among other metrics, average sum- rate and outage probability.
