Prospects and challenges of free space optical communications
(
Springer Verlag
, 2018 , Conference Paper)
Free space optical (FSO) transmission is a technology which uses a narrow laser beam to transmit the signal from the source to the destination through the free space. Although it has various advantages, a laser beam ...
Outage performance of multi-hop hybrid FSO/RF communication systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ...
Stability and global dissipativity for neutral-type fuzzy genetic regulatory networks with mixed delays
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Article)
In this article, the stability and global dissipativity for neutral-type fuzzy genetic regulatory networks (FGRNs) with mixed time delays are investigated. By using Lyapunov functional method and linear matrix inequalities ...
