This paper addresses the beamforming and power allocation problem in the downlink multi-
input multi-output (MIMO) non-orthogonal multiple access (NOMA) based cognitive radio …

Integrating non-orthogonal multiple access (NOMA) in intelligent reflecting surface (IRS) is
expectedly an effective solution to enhance system's spectrum efficiency. In this paper, we …

Cognitive radio-based non-orthogonal multiple access (CR-NOMA) is considered to be one
of the promising multiple accessing technique candidates for 5G and beyond networks …

In this paper, we derive the throughput of non-orthogonal multiple access NOMA with
adaptive transmit power for cognitive radio networks (CRN). The secondary source and …

Cognitive radio is a promising technique for efficient spectrum utilization in wireless systems.
In this paper, we consider a multiple-input multiple-output (MIMO) underlay cognitive radio …

In this work, coordinated beamforming and power allocation schemes are proposed for
multicell downlink non-orthogonal multiple access (NOMA) systems. Beamforming is …

In this paper, a novel MIMO-NOMA framework for downlink and uplink transmission is
proposed by applying the concept of signal alignment. By using stochastic geometry, closed …

We address the problem of power allocation and secondary user (SU) selection in the
downlink from a secondary base station (SBS) equipped with a large number of antennas in …

In this paper, we consider joint beamforming, power, and channel allocation in a multiuser
and multichannel underlay multiple-input-single-output (MISO) cognitive radio network …

In this letter, a underlay cognitive radio inspired non-orthogonal multiple access (CR-NOMA)
network assisted by the reconfigurable intelligent surface (RIS) technique is conceived to …
