UAV-assisted cooperative downlink NOMA with virtual full-duplex operation

open access: yesICT Express, 2019
In this paper, we consider an unmanned aerial vehicle (UAV)-assisted downlink cellular network consisting of a single base station (BS), two mobile stations (MSs) with N antennas, and K UAV relay stations (RSs). We assume that there exists no direct link

Non-Orthogonal Multiple Access (NOMA) to Enhance Capacity in 5G

open access: yesInternational Journal of Contents, 2015
Non-orthogonal multiple access (NOMA) where all users share the entire time and frequency resource has paid attention as one of the key technologies to enhance the spectral efficiency and the total throughput. Nevertheless, as the number of users and SIC error increase, the inter-user interference and the residual interference due to the SIC error also
