Multi-hop hybrid FSO/RF communication systems
Kazemi, Hossein (2014-08)The reliability of free-space optical (FSO) links is severely restricted by weather-dependent atmospheric phenomena including absorption, scattering and turbulence. An efficient solution is to build hybrid links where a ... -
Outage analysis of hybrid FSO/RF systems based on finite-state Markov Chain modeling
Kazemi, Hossein; Uysal, Murat; Touati, F. (IEEE, 2014)In this paper, we analyze the outage probability of a hybrid free-space optical/radio-frequency (FSO/RF) communication system with soft-switching. In soft-switching approach, either one of the links or both links can be ... -
Outage performance of MIMO free-space optical systems in gamma-gamma fading channels
Kazemi, Hossein; Mostaani, Zohreh; Uysal, Murat; Ghassemlooy, Z. (IEEE, 2013)In this paper, we consider a MIMO Free-Space Optical (FSO) communication system over gamma-gamma turbulence channels and derive a closed-form analytical expression for the outage probability taking into account the effects ... -
Performance analysis of MIMO free-space optical communication systems with selection combining
Kazemi, Hossein; Uysal, Murat (IEEE, 2013)In this paper, we investigate the outage performance of a multi-input multi-output (MIMO) free-space optical (FSO) communication system with selection combining (SC). Under the assumption of log-normal distributed atmospheric ...
