In this paper, we investigate the physical layer security for a cognitive multiuser network
which is composed of multiple cognitive sources, a cognitive destination and an …

This paper addresses the challenge of improving the digitalisation of 5G communications,
with multiple-input-multiple-output (MIMO) non-orthogonal multiple access (NOMA) systems …

This paper addresses the problem of centralized transceiver design for multiuser MIMO
amplify-and-forward (AF) relaying within a cloud radio access network (C-RAN). The aim is …
