In this study, the authors present and investigate a novel cooperative relaying scheme for
cognitive radio networks (CRNs), which is based on non‐orthogonal multiple access …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient technology to
satisfy the massive data requirement of the next-generation wireless communication …

In this article, we investigate a selective decode-and-forward (DF)-aided cooperative
nonorthogonal multiple access (NOMA) system performance in the presence of practical …

This paper studies the application of cooperative techniques for non-orthogonal multiple
access (NOMA). More particularly, the fixed gain amplify-and-forward (AF) relaying with …

Non-orthogonal multiple access (NOMA) and spectrum sharing (SS) are two emerging
