This work presents a theoretical investigation on the per-
formance of directly modulated/detected (DM/DD) optical orthogonal
frequency division multiplexed (OOFDM) systems subject to optical filter-
ing. The impact of ...

En este trabajo se realiza una intensiva labor teórica de descripción de sistemas de comunicaciones ópticas que utilizan la técnica de multiplexación por división de frecuencias ortogonales (OFDM en inglés), más concretamente ...
Sánchez Costa, Christian(Universitat Politècnica de València, 2013-06-18)
[ES] Se propone el empleo de una modulación de fase óptica para mejorar las prestacíones de un sistema óptico OOFDM. Utilizando un modelo óptico de un sistema OOFDM programado en Matlab/VPI, se demuestra la mejora en ...
