Unprecedented growth in wireless data traffic, and ever-increasing demand for highly
secured, and low-latency wireless communication has motivated the research community to …

It has been predicted that by the year 2030, 5G and beyond 5G (B5G) networks are
expected to provide hundreds of trillions of gigabytes of data for various emerging …

In this paper, we consider max-min fairness for a downlink two-user multi-input single-output
(MISO) system with imperfect channel state information available at transmitter (CSIT) taking …

In this work, we address the problem of a joint robust transmission, reflection and reception
strategy design at an active reconfigurable intelligent surface (RIS)-assisted underlay …

This paper develops a tractable analysis framework to evaluate the reliability and security
performance of cooperative non-orthogonal multiple access (co-NOMA) in cognitive …

Cognitive radio networks (CRNs) have emerged as a reliable technology to address the
problem of spectrum under-utilization. Cognitive radio (CR) is known to be intelligent, as it …

In this paper, we investigate the power allocation for maximizing weighted sum rate (WSR)
in downlink multiple carriers non-orthogonal multiple access (MC-NOMA) systems with …

Owing to the eminent performance gain, non-orthogonal multiple access (NOMA) has been
regarded as a promising approach to achieve high throughput and low latency for the next …

The physical layer security (PLS) has become crucial in the fifth generation (5G) wireless
technology where non-orthogonal multiple-access (NOMA) plays an essential role for …

The implementation of advanced communication technologies such as nonorthogonal
multiple access technologies (NOMA) and cognitive radio (CR) technology in the Internet of …
