In the fifth generation (5G) wireless communication system, the non‐orthogonal multiple
access (NOMA) scheme has recently been proposed as a possible candidate for improving …

As energy efficiency (EE) is a key performance indicator for the future wireless network, it
has become a significant research field in communication networks. In this paper, we …

This paper introduces a new multiuser communication model, which we call multiple access
diamond channel. In this channel model, many sources transmit their signals to a destination …

This paper investigates the power control and routing problem in the communication
process of an energy harvesting (EH) multi-hop cognitive radio network (CRN). The …

In real communication systems, secure and low-energy transmit scheme is very important.
So far, most of schemes focus on secure transmit in special scenarios. In this paper, our goal …

Future communications are developed with new communication standards for multi access
technologies, where spectrum sharing and Non-orthogonal multiple access (NOMA) are the …

To meet the demands of future generation wireless communications, Non-Orthogonal
Multiple Access (NOMA) and Cognitive Radio (CR) are emerging technologies. In exchange …
