Secure transmission for uplink and downlink non-orthogonal multiple access system with imperfect channel state information
In this paper, we design a secure transmission scheme in uplink and downlink of non-orthogonal multiple access (NOMA) system. In this scenario, two pairs of base station-user can operate under the presence of eavesdropper. The relay plays an…
