Wireless Powered Cooperative Relaying using NOMA with Imperfect CSI
Dinh-Thuan Do, Mojtaba Vaezi, Thanh-Luan Nguyen
The impact of imperfect channel state (CSI) information in an energy harvesting (EH) cooperative non-orthogonal multiple access (NOMA) network, consisting of a source, two users, a…
Non-Orthogonal Multiple Access: Common Myths and Critical Questions
Mojtaba Vaezi, Robert Schober, Zhiguo Ding +1
Non-orthogonal multiple access (NOMA) has received tremendous attention for the design of radio access techniques for fifth generation (5G) wireless networks and beyond. The basic…
Impact of Beam Misalignment on Hybrid Beamforming NOMA for mmWave Communications
Mojtaba Ahmadi Almasi, Mojtaba Vaezi, Hani Mehrpouyan
This paper studies hybrid beamforming (HB)-based non-orthogonal multiple access (NOMA) in multiuser millimeter wave (mmWave) communications. HB offers power-efficient and low-compl…
Securing Downlink Non-Orthogonal Multiple Access Systems by Trusted Relays
Ahmed Arafa, Wonjae Shin, Mojtaba Vaezi +1
A downlink single-input single-output non-orthogonal multiple access system is considered in which a base station (BS) is communicating with two legitimate users in the presence of…
