This paper proposes and investigates an overlay spectrum sharing system in conjunction
with the simultaneous wireless information and power transfer to enable communications for …

This paper focuses on designing robust symbol-level precoding (SLP) in an overlay
cognitive radio (CR) network, where the primary and secondary networks transmit signals …

The authors consider co-existence of a secondary network with a primary network under an
overlay framework and propose beamformer design and power allocation using an iterative …

Recently, there has been an increasing interest in investigating the impact of dual
shadowing processes on the performance of wireless fading channels. Conveniently, these …

In this paper, a mixture gamma (MG) distribution that is highly accurate unified approximate
approach is used to model the intractable statistical properties of α-κ-μ shadowed fading …

In the recent years, wireless applications and services have grown tremendously, resulting
to a shortage of radio spectrum. On one hand, most of the available radio spectrum has …

Cognitive radio (CR) is a newly developed technology for increasing spectral efficiency in
wireless communication systems. In the CR networks, there exist two traditional spectrum …

In this paper, novel closed-form expressions for the level crossing rate and average fade
duration of κ-μ shadowed fading channels are derived. The new equations provide the …

We propose the joint resource allocation and admission control schemes for energy-
harvesting (EH) based cooperative overlay cognitive radio networks under imperfect …

This paper studies overlay-based cognitive radio networks (ObCRNs) where transmission
from a licensed transmitter (LT) to a licensed receiver (LR) is supported by an unlicensed …
