An assessment of a unmanned aerial vehicle-based broadcast scenario assuming random terrestrial user locations
(2021)With the advent of the new decade, unmanned aerial vehicles (UAVs) will increasingly play an active role mainly as broadband transmission relays for broadcast applications. In the present study, we consider a feasible ... -
Cache-assisted interference cancellation in the multi-user downlink fading channel and its application in HetNets
(2019)Next generation wireless systems will be characterized by two things among others: the dense deployment of small cell base stations (SBS), and caching of popular data files at the edge. In this paper we study the downlink ... -
Cascaded Composite Turbulence and Misalignment: Statistical Characterization and Applications to Reconfigurable Intelligent Surface-Empowered Wireless Systems
(2022)Reconfigurable intelligent surfaces (RISs) empowered high-frequency wireless systems are expected to become the supporting pillar for several reliability and data rate hungry applications. Such systems are, however, sensitive ... -
Enhancing QoS Through Fluid Antenna Systems over Correlated Nakagami-m Fading Channels
(2022)Fluid antenna systems (FAS) enable mechanically flexible antennas that offer adaptability and flexibility for modern communication devices. In this work, we present a conceptual model for a single-antenna N-port (SANP) FAS ... -
Exploring the Random Location Problem Inside a Truncated Conic Shape: Application in UAV Communications
(2022)More often than not, transmitters (Txs) in wireless networks operate using directional radiation patterns where the main radiation lobe creates a three-dimensional conic-shaped volume. In this context, any receiver (Rx) ... -
New results on turbulence modeling for free-space optical systems
(2010)In this paper, we propose a statistical channel model, named as Double-Weibull, to describe the irradiance fluctuations in moderate and strong turbulence for free-space optical (FSO) systems. The proposed stochastic model ... -
On the inverse-Gaussian shadowing
(2011)The Inverse Gaussian (IG) distribution has been recently proposed as a less complex alternative to the classical log-normal distribution to describe shadowing phenomena. This paper investigates the performance of digital ... -
Outage Analysis and Realization Challenges of RIS-enabled Underlay CR Networks over Nakagami-m Fading
(2022)Metamaterials, i.e., reconfigurable intelligent surfaces (RISs), have become very promising and advancing rapidly due to the ability to manipulate electromagnetic (EM) waves. This feature essentially ensures the versatile ... -
Outage Probability of a Multisensor Mixed UOWC-FSO Setup
(2019)The performance of a network consisting of several underwater sensors communicating with a terrestrial destination is studied for the first time in terms of the outage probability. In the scenario under consideration, K ... -

Performance of an Underwater Optical Wireless Link with a Randomly Placed or Moving Receiver
(2021)The current work investigates the outage probability of a vertical diffused line-of-sight underwater optical wireless communication link where a fixed transmitter at the sea surface communicates with a receiver floated ... -
Performance of free-space optical communications over a mixture composite irradiance channel
(2017)The performance of a typical free-space optical link using a recently proposed composite model for turbulence and pointing error effects is studied. This model offers analytical tractability in the statistical description ... -
Α dual-hop equivalent structure of a generalised multi-hop free-space optics network
(2021)The performance of free-space optics links strongly depends on scintillation effects caused by the atmospheric turbulence appearance. A widely adopted way to counterbalance the expected deterioration due to scintillation ...
