Cognitive Radio and the emerging Non-Orthogonal Multiple Access (NOMA) techniques
hold the potential to fulfill the increasing demands of radio spectrum by 5G-and-B5G …

In this paper, we address the antenna selection (AS) problem in full-duplex (FD) cooperative
non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay bridges …

The performance of a downlink non‐orthogonal multiple access based cooperative network
with maximum ratio transmission/receive antenna selection (MRT/RAS) over Nakagami‐m …

Cooperative communication combining non-orthogonal multiple access (NOMA) and
cognitive radio is a rapidly growing technique for wireless networks and beyond 5G Still …

Nonorthogonal multiple access (NOMA) is one of the most promising multiple access
techniques in fifthgeneration and beyond (5G+). It can satisfy the increase in demands of …

In this paper, we examine non-orthogonal multiple access (NOMA) and relay selection
strategy to benefit extra advantage from traditional cognitive radio (CR) relaying systems …

In this paper, we investigate a non-orthogonal multiple access (NOMA) scheme with partial
relay selection in underlay cognitive radio networks. We consider a cognitive cooperative …
