Enhancing secrecy capacity in FSO links via MISO systems through turbulence-Induced fading channels with misalignment errors
Boluda-Ruiz, Rubén
; Tokgoz, Sezer C.; García-Zambrana, Antonio; Qaraqe, Khalid (Institute of Electrical and Electronics Engineers, 2020-08)
It has recently been proved that the free-space optical (FSO) communication links are susceptible to interceptions. Due to this reason, the optics community shows a special interest in studying these high-speed links in ... -
Impulse response modeling of underwater optical scattering channels for wireless communication
Boluda-Ruiz, Rubén; Rico-Pinazo, Pedro; Castillo-Vázquez, Beatriz; García-Zambrana, Antonio; Qaraqe, Khalid (Institute of Electrical and Electronics Engineers, 2020-08)
Despite the fact that underwater optical wireless communication (UOWC) systems are able to provide high-data rate links with high security, the performance of these systems presents several limitations related to the maximum ... -
Outage capacity of rate-adaptive relaying for FSO links with nonzero boresight pointing errors
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen; Qaraqe, Khalid; qaraqe[et al.] (Institute of Electrical and Electronics Engineers, 2019-03-20)
An outage capacity analysis of a three-way free-space optical (FSO) setup based on the optical path selection, either source-destination (S-D) or source-relay-destination (S-R-D), with a greater value of channel gain along ... -
Secure communication for FSO links in the presence of eavesdropper with generic location and orientation
Boluda-Ruiz, Rubén; Castillo-Vázquez, Beatriz; García-Zambrana, Antonio; Qaraqe, Khalid (Optica Publishing Group, 2019)
When the beam waist at the receiver is significantly larger than the receiver size, free-space optical (FSO) links may be vulnerable to some optical tapping risks at the physical layer. In this paper, we conduct a new ... -
Statistical Channel Impulse Response Modeling for Optical Wireless Communication in Turbid Waters
Boluda-Ruiz, Rubén; Rico-Pinazo, Pedro; Castillo-Vázquez, Beatriz; García-Zambrana, Antonio; Qaraqe, Khalid (URSI'19 (Sevilla, septiembre, 2019), 2019)
Underwater optical wireless communication (UOWC) systems support high-speed, reliable and cost-effective implementations that are demanded for extending the telecommunication networks to oceans. UOWC systems suffer from ...
