Low Complexity DSP for High Speed Optical Access Networking
(Mdpi, 2021-04-01)
A novel low-cost and energy-efficient approach for reaching 40 Gb/s signals is proposed for cost-sensitive optical access networks. Our proposed design is constituted of an innovative low-complex high-performance digital ...
Harnessing machine learning for fiber-induced nonlinearity mitigation in long-haul coherent optical OFDM
(2018-12-20)
Coherent optical orthogonal frequency division multiplexing (CO-OFDM) has attracted a lot of interest in optical fiber communications due to its simplified digital signal processing (DSP) units, high spectral-efficiency, ...
Study of the glass transition temperature of as-s glasses for the fabrication of chalcogenide optical fibers
(2013-09-01)
Values of glass transition temperature (Tg) and of linear expansion coefficient (α) for Asx S100-x glasses were measured in the range of concentrations 35 × 42. Because of the importance of the glass formation region 35 × 42 ...

Equalização neural aplicada a sistemas com modulação bidimensional em fibra óptica
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2014-02-28)
Nowadays, optic fiber is one of the most used communication methods, mainly due to
the fact that the data transmission rates of those systems exceed all of the other means of
digital communication. Despite the great ...
