Design and implementation of low complexity adaptive optical OFDM systems for software-defined transmission in elastic optical networks Nadal Reixats, Laia (Universitat Politècnica de Catalunya, 2014-11-21)
Open AccessDue to the increasing global IP traffic and the exponential growing demand for broadband services, optical networks are experimenting significant changes. Advanced modulation formats are being implemented at the Digital ...
Locatelli, Fabiano; Christodoulopoulos, Kostantinos; Fàbrega Sánchez, Josep Maria; Svaluto Moreolo, Michela; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2020)
Open AccessWe propose a method to estimate the central frequency and the bandwidth of optical filters, that relies on optical spectra captured with optical channel monitors at ROADM’s ingress port. We demonstrate for both features ...
Low complexity PAPR reduction techniques for clipping and quantization noise mitigation in direct-detection O-OFDM systems Nadal Reixats, Laia; Svaluto Moreolo, Michela; Fàbrega Sánchez, Josep Maria; Junyent Giralt, Gabriel (2014-06-01)
Restricted access - publisher's policyWe present different distortionless peak-to-average power ratio (PAPR) reduction techniques that can be easily applied, without any symmetry restriction, in direct-detection (DD) optical orthogonal frequency division ...
Performance analysis of optical OFDM transmission systems using PAPR mitigation techniques and alternative transforms Nadal Reixats, Laia (Universitat Politècnica de Catalunya, 2012-04-25)
Open Access[ANGLÈS] Optical orthogonal division multiplexing (OFDM) has recently been introduced in optical communications because of its robustness against channel dispersion and its high spectral efficiency. OFDM is based on the ...
