Journal ArticleDOI
Mixed RF/FSO Relaying With Outdated Channel State Information
TL;DR: Numerical and simulation results show that there is an optimal value of the transmitter beam waist, which minimizes the overall outage probability, and this optimal value strongly depends on the pointing errors standard deviation.
Journal ArticleDOI
Partial Relay Selection With Outdated Channel State Estimation in Mixed RF/FSO Systems
TL;DR: The results illustrate that the outdated CSI used for the relay selection has a strong effect on the system performance, especially in weak turbulence conditions of the FSO hop, and the improvement of the systemperformance with increase of the number of the relays is highly dependent on the F SO channel state.
Journal ArticleDOI
SIMO optical wireless links with nonzero boresight pointing errors over M modeled turbulence channels
TL;DR: The turbulence-induced fading of the received optical signal irradiance is studied through the M (alaga) distribution, which is an accurate model suitable for weak to strong turbulence conditions and unifies most of the well-known, previously emerged models.
Journal ArticleDOI
Outage capacity of FSO link with pointing errors and link blockage.
TL;DR: The numerical and simulation results show that the link blockage causes appearance of the outage floor that is a significant energetic characteristic of an FSO system and there exists an optimal value of the laser beam radius at the waist for minimizing outage probability in order to achieve the specified outage capacity.
Journal ArticleDOI
Outage Performance of the Mixed RF/FSO Relaying Channel in the Presence of Interference
TL;DR: Novel closed-form expressions for the outage probability of the amplify-and-forward dual-hop semi-blind relaying channel, composed of mixed radio frequency (RF)/free space optical (FSO) links, while the relay is corrupted by both co-channel interferences and noise.
