Adaptive selective relaying in cooperative free-space optical systems over atmospheric turbulence and misalignment fading channels
Boluda-Ruiz, Rubén
; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (Optica Publishing Group, 2014)
In this paper, a novel adaptive cooperative protocol with multiple relays using detect-and-forward (DF) over atmospheric turbulence channels with pointing errors is proposed. The adaptive DF cooperative protocol here ... -
Análisis de la capacidad ergódica en sistemas cooperativos de comunicaciones ópticas no guiadas
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (2015-09-14)
Ergodic capacity for the bit-detect-and-forward (BDF) cooperative protocol over gamma-gamma fading channels with pointing errors is here analyzed. Novel closed-form approximate ergodic capacity expression is here obtained ... -
Análisis de técnicas de diversidad espacial adaptadas al canal óptico submarino en presencia de dispersión y turbulencia oceánica.
Salcedo-Serrano, Pedro; Garrido-Balsells, José María; García-Zambrana, Antonio; Puerta-Notario, Antonio; Castillo-Vázquez, Beatriz; Boluda-Ruiz, Rubén[et al.] (2023)
High absorption and scattering of the seawater impose new challenges in the design of novel underwater optical wireless transceivers. This paper presents a comprehensive comparison in terms of BER of Multiple-Input/Single-Output ... -
Analysis of complex amplitude modulation with checkerboard-type holograms in phase-only modulators.
Puerta-Notario, Antonio; Schröder Antúnez, Lucía de Fátima; Garrido-Balsells, José María; Boluda-Ruiz, Rubén; Castillo-Vázquez, Beatriz; García-Zambrana, Antonio[et al.] (2024)
For the generation of optical propagation modes using a phase-only spatial light modulators, it is essential that both phase and amplitude components of their complex fieldsare encoded. In this paper, we obtain the complete ... -
Evaluating pointing errors on ergodic capacity of DF relay-assisted FSO communication systems
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (2015-09-15)
Ergodic capacity of decode-and-forward (DF) relay-assisted free-space optical (FSO) communication systems when line of sight is available is analyzed over gamma-gamma fading channels with pointing errors. Novel closed-form ... -
Impact of nonzero boresight pointing error on ergodic capacity of MIMO FSO communication systems
Boluda-Ruiz, Rubén; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen; García-Zambrana, Antonio (Optica Publishing Group, 2016)
A thorough investigation of the impact of nonzero boresight pointing errors on the ergodic capacity of multiple-input/multiple-output (MIMO) free-space optical (FSO) systems with equal gain combining (EGC) reception under ... -
Novel approximation of misalignment fading modeled by Beckmann distribution on free-space optical links
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Beatriz; Castillo-Vázquez, Carmen (Optica Publishing Group, 2016)
A novel accurate and useful approximation of the well-known Beckmann distribution is presented here, which is used to model generalized pointing errors in the context of free- space optical (FSO) communication systems. We ... -
Outage Performance of Exponentiated Weibull FSO Links Under Generalized Pointing Errors.
Boluda-Ruiz, Rubén; García-Zambrana, Antonio; Castillo-Vázquez, Carmen; Castillo-Vázquez, Beatriz; Hranilovic, Steve (IEEE, 2017)
Even in clear conditions, free-space optical (FSO) links are impaired by scintillation and dynamic misalignment which result in a slow fading channel. This paper presents the first characterization of outage performance ... -
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 ...
