This paper theoretically and experimentally investigate the spectrum attenuation of free
space optical (FSO) communication systems operating at visible and near infrared (NIR) …

A multiuser dual-hop relaying system over mixed radio frequency/free-space optical
(RF/FSO) links is investigated. Specifically, the system consists of m single-antenna sources …

This paper presents novel experimental results for a 10 Gb/s triple-hop relay-based all-
optical free space optical (FSO) system by employing the amplify-and-forward relaying …

Free-space optical (FSO) communication can be seen as a promising technology for point-to-
point and back-hauling links in the next generation wireless networks (5G and beyond) …

In order to study and compare propagation features of Terahertz (THz) and infrared (IR) links
under different air turbulence conditions, THz and IR free-space communication links at 625 …

In this letter, two methods for characterizing fog attenuation in terms of atmospheric visibility
V in free space optics (FSO) communications are analyzed and compared. Both methods …

Fog has a strong attenuation effect on the optical channel, which will greatly degrade the
performance of visible light communication (VLC). Studying the effect of the fog on …

We propose a new approach for high-fidelity free-space optical data transmission through
dynamic smoke using a series of 2D arrays of random numbers as information carriers. Data …

In this paper, we investigate the performance of a vehicular visible light communications
(VVLC) link with a non-collimated and incoherent light source (a light-emitting diode) as the …

In this paper we introduce a simple and effective method for substantially reducing the beam
spot wandering and scattering effects in the free space optical (FSO) communications using …
