In this paper, we study the application of the non orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …
A novel opportunistic semantic and bit communication strategy is proposed for uplink non- orthogonal multiple access (NOMA). Specifically, a secondary far user (F-user) employs …
Non-orthogonal multiple access (NOMA) is a Fifth Generation (5G) technique that allows many users to simultaneously access the same time–frequency separating channels via …
Due to the increasing number of devices to be connected in fifth-generation (5G) and Internet of Things (IoT) networks, spectrum efficiency becomes a very challenging issue …
This paper investigates the performance of cooperative networks based on non-orthogonal multiple access (NOMA) with multiple full-duplex decode-and-forward relays. Taking into …
