This thesis considers various cognitive radio-based non-orthogonal multiple access (CR-
NOMA) applications by focusing on the efficient usage of communication technologies, such …

The next‐generation communication systems demand huge spectral and energy efficiency,
low latency, high scalability, improved connectivity and reliability, as well as advanced …

In the realm of 5G mobile wireless communication, cognitive radio (CR) plays an important
role in improving radio spectrum efficiency by overcoming challenges such as spectrum …

Recently, the increasing demand of radio spectrum for the next generation communication
systems due to the explosive growth of applications appetite for band-widths has led to the …

The rapid growth in the use of mobile devices and wireless services has led to a shortage of
available spectrum for communication. To solve this issue, Cognitive Radio (CR) has been …

In this paper, cognitive radio (CR) based on non-orthogonal multiple access (NOMA) is
considered over frequency non-selective Rayleigh fading channels. The two techniques are …

Due to the increasingly complicated communication scenarios and network architectures as
well as growing traffic demands for high speed connectivity, dynamic spectrum allocation in …

Due to the increasingly complicated communication scenarios and network architectures as

In this paper, multi‐users (MU) communications are considered based on the cognitive ratio
(CR) technique. Multiple‐input multiple‐output (MIMO) and non‐orthogonal multiple access …

In this paper, we optimise the throughput of cooperative non orthogonal multiple access
(NOMA) for cognitive radio networks (CRN). The secondary nodes harvest energy using the …
