Abstract
Non-orthogonal multiple access (NOMA) has emerged as a new multiple access paradigm for 5G wireless networks. Although many results have been produced for NOMA, most of them are limited to theoretical exploration and performance analysis. A limited progress is made in employing NOMA schemes into a realistic scenario. In this paper, we introduce a downlink power-domain NOMA (PD-NOMA) into a realistic transmission. We first design a cell area where we randomly deployusers around a base station (BS). The BS has the ability to identify the best NOMA pairs, Namely, near and far users, among all users. The BS will then allocate the power to both near and far users. Our zero forcing (ZF)-aided successive interference cancellation (SIC) detector is capable of successfully removing the interference of the near user signals as documented in the bit error ratio (BER) results.
