Capacity Enhanced Cooperative D2D Systems over Rayleigh Fading Channels with NOMA
Wei Duan, Jinjuan Ju, Qiang Sun +4
This paper considers the cooperative device-to-device (D2D) systems with non-orthogonal multiple access (NOMA). We assume that the base station (BS) can communicate simultaneously…

Use of Non-Orthogonal Multiple Access in Dual-hop relaying
Wei Duan, Miaowen Wen, Yier Yan +2
To improve the sum-rate (SR) of the dual-hop relay system, a novel two-stage power allocation scheme with non-orthogonal multiple access (NOMA) is proposed. In this scheme, after t…

Low-Complexity QL-QR Decomposition Based Beamforming Design for Two-Way MIMO Relay Networks
Wei Duan, Wei Song, Moon Ho Lee
In this paper, we investigate the optimization problem of joint source and relay beamforming matrices for a twoway amplify-and-forward (AF) multi-input multi-output (MIMO) relay sy…
