In this paper, the performance of a mixed Terahertz/free-space optical (THz/FSO) wireless transmission system is studied, where joint effects channel fading and pointing errors are considered for both THz FSO links. Employing semi-blind amplify-and-forward protocol, we derive cumulative distribution function probability density end-to-end signal-to-noise ratio. By applying derived statistics, e...

Optical wireless communication (OWC) is one of the promising solution to enhance capacity next generation cellular as well fiber-wireless (FiWi) broadband access networks.

This is done for an FSO link under different weather conditions at 1.55 μm. Under practi...

OBJECTIVES Occlutech Figulla ASD Occluder (FSO) is an alternative device to Amplatzer Septal Occluder (ASO) with some structural innovations including increased flexibility, minimizing the amount of material implanted, and absence of the left atrial clamp. We aimed to report our experiences with FSO and compare the outcomes of this novel device versus ASO. INTERVENTIONS Between December 2005 ...

This paper investigates the average symbol error rate (ASER) performance of a dualhop hybrid relaying system relying on both radio frequency (RF) and free space optical (FSO) links. Specifically, the RF link is used for supporting mobile communication, while the FSO link is adopted as the backhaul of the cellular infrastructure. Considering non-line-of-sight (NLoS) RF transmissions and a genera...

Free space optics (FSO) is a promising solution for the need to very high data rate point-to point communication. FSO communication technology became popular due to its large bandwidth potential, unlicensed spectrum, excellent security and quick and inexpensive setup. Unfortunately, atmospheric turbulence-induced fading is one of the main impairments affecting FSO communications. To design a hi...

<span lang="EN-US">Free-space optical (FSO) communication can provide the cost-efficient, secure, high data-rate links required for applications. For example, it provides broadband internet access and backhauling fifth-generation (5G) sixth-generation (6G) networks. However, previous solutions to deal with signal loss caused by obstructions atmospheric turbulence. In these solutions, reco...

Free Space Optics is a line of sight communication which transmits very narrow beam width. FSO offers high bandwidth and higher data rate up to 10 Gbps. units are transportable, compact easy redeploy. With so many advantages there exists serious limitations atmospheric effects makes it inefficient for long reach transmission. Environment factors act as barriers in efficient utilization technolo...
