Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

It is widely believed that the advances of networking technologies will reshape the future of
telecommunication system. The continuous growth in data traffic originated by mobile users …

Cognitive radio (CR) has been considered as a potential candidate for addressing the
spectrum scarcity problem of future wireless networks. Since its conception, several …

The spectrum sensing performance depends on the accuracy of the detection about whether
primary users are busy or idle. Previous studies on cognitive radio spectrum sensing have …

In this paper, we investigate the performance of energy detection-based spectrum sensing
over F composite fading channels. To this end, an analytical expression for the average …

With the advent of Sixth Generation (6G) telecommunication systems already envisioned,
increased effort is made to further develop current communication technologies, so they can …

Cognitive radio (CR), as a concept based on the ability to detect and share the unutilised
spectrum, has been envisioned as a promising candidate to improve the efficiency of …

This study investigates the unified performance analysis of an energy detector (ED) over α-η-
μ/IG and α-κ-μ/IG generalized fading channels. The probability density functions (PDF) of the …

One of the most important factors that affects the performance of energy detection (ED) is the
fading channel between the wireless nodes. This paper investigates the performance of ED …

During the last decades, wireless communications have evolved from a scarce technology,
used by professionals for niche applications to a rapidly advancing research field. Ever …
