This paper explores joint power allocation and route selection in a multihop cognitive radio
network consisting of secondary transmitter and receiver connected through decode-and …

Non-orthogonal multiple access (NOMA) is one of the most significant technologies to meet
the demand of high spectral efficiency (SE) in the fifth generation (5G) cellular networks. The …

In this paper, we propose a joint beamforming and power-splitter optimization technique for
simultaneous wireless power and information transfer in the downlink transmission of a …

We study a wireless-powered uplink communication system with non-orthogonal multiple
access (NOMA), consisting of one base station and multiple energy harvesting users. More …

In this paper, the performance of opportunistic relay selection (ORS) in a cognitive radio is
analyzed over flat Rayleigh fading channels. Data transmission between source and …

In this paper, we investigate a dual hop communication decode-and-forward relaying system
where a source node wants to transmit two symbols to its two desired destinations with the …

A decentralized channel access strategy is proposed for a multichannel low-power cognitive
radio (CR) system. CRs are equipped with rechargeable batteries to harvest radio-frequency …

To further improve spectral efficiency, this paper considers a non-orthogonal multiple access
(NOMA)-assisted overlay cognitive radio network consisting of a pair of primary users and a …

In this paper, we design a NOMA-based spectrum leasing scheme by considering the
following three assumptions for the successive interference cancellation (SIC):(i) the primary …

In this paper, we propose an improved cognitive radio (CR) model in which the secondary
system can harvest energy from the primary system and access the spectrum of the primary …
