recommendations! Published in 2020 at "IEEE Access"

DOI: 10.1109/access.2020.3030221

Abstract: This article studies the wireless systems by implementing the full-duplex (FD) unmanned aerial vehicle (UAV) relay to allow two nearby base stations joint communicate to distant users. The non-orthogonal multiple access (NOMA) assisted networks and… read more here.
