For the last few decades, wireless communication has been facing a technological
revolution. High data rate and continuous connectivity are the necessities because the …

The non-orthogonal multiple access (NOMA) system is considered an important technology
that enables the fifth-generation (5G) wireless systems and beyond to satisfy different …

Presently, Non-Orthogonal Multiple Access (NOMA) frequently uses Successive Interference
Cancellation (SIC) with channel estimation to detect the receivers' signal successfully …

Position awareness is very important for many sensor network applications. However, the
use of Global Positioning System receivers to every sensor node is very costly. Therefore …

This paper investigates the opportunistic sharing of relay for the proposed Non-Orthogonal
Multiple Access (NOMA) assisted Cognitive Radio Networks (CRNs). The proposed scheme …

The deployment of Secondary Networks (SNs) gives an energy and cost-saving outcome for
service providers. The existing research on SNs is gleaned from capacity enhancement …

Non-orthogonal multiple access (NOMA) systems can serve multiple users in contrast to
orthogonal multiple-access (OMA), which makes use of the limited time or frequency domain …

Abstract Presently, Secondary Networks (SNs) are gleaned from rising capacity with
reducing interference together instead of making them energy-efficient for green …

This paper is concerned with a cognitive cloud radio access network (CRAN) with a special
attention to efficient and reliable downlink transmission of big data for secondary users …

The NOMA (non-orthogonal multiple access) techniques developed in the context of 5G
networks allows several users to share the same frequency band simultaneously. The main …
