Atmospheric Attenuation and Scintillation Effects on the Range of EDM Instruments

Garrido-Villén, Natalia; Antón Merino, Alberto; Berné Valero, José Luis; Mata, Rafael; Raboso García-Baquero, David (American Society of Civil Engineers, 2015-08)

This investigation aimed to study the range of various electronic distance measurement (EDM) instruments used in survey engineering, assuming different weather conditions and different terrain altitudes, by controlling ...
On N-PAM and M-QAM implementation within the hybrid RoF-FSO-PON system

Nguyen, Dong-Nhat; Zvanovec, Stanislav; Bohata, Jan; Ortega Tamarit, Beatriz; Vallejo-Castro, Luis; Ghassemlooy, Zabih (IEEE, 2020-11-25)

[EN] This paper investigates an optical transmission architecture of a passive optical network (PON), which is compatible with the millimeter-wave radio-over-fiber and free-space optics systems (RoF-FSO) under weak-to-strong ...
Photonic Millimeter Wave Signal Generation and Transmission Over Hybrid Links in 5G Communication Networks

Vallejo Castro, Luis (Universitat Politècnica de València, 2022-11-28)

[ES] El estándar de quinta generación (5G) es la clave potencial para satisfacer el aumento exponencial en la demanda de nuevas aplicaciones, servicios y usuarios. La tecnología 5G ofrecerá una latencia extremadamente baja ...
Photonic multiple millimeter wave signal generation and distribution overreconfigurable hybrid SSMF/FSO links

Vallejo-Castro, Luis; Ortega Tamarit, Beatriz; Bohata, Jan; Zvanovec, Stanislav; Almenar Terre, Vicenç (Elsevier, 2020-01)

[EN] Microwave photonics provides attractive solutions for millimeter wave (mmW) signal generation. In this paper, we demonstrate photonically generated multiple mmW signals transmission over a wavelength division multiplexed ...
Transmission of 2 bits/symbol over RoF and RoFSO links with different architectures for ubiquitous coverage

Nguyen, Dong-Nhat; Zvanovec, Stanislav; Vallejo-Castro, Luis; Ortega Tamarit, Beatriz; Bohata, Jan; Ghassemlooy, Zabih (IEEE, 2020-07-22)

[EN] This paper investigates integrated radio-over-fiber and radio-over-free-space optic links in a passive optical network architecture for ubiquitous wireless coverage. Two optical millimeter-wave generation techniques, ...
