Title (EN) DIMMABLE DC-BIASED OPTICAL ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING
(FR) MULTIPLEXAGE PAR RÉPARTITION ORTHOGONALE DE LA FRÉQUENCE OPTIQUE POLARISÉ PAR COURANT CONTINU À INTENSITÉ RÉGLABLE
Abstract:
(EN) A computer implemented method, system, and device for direct-current biased optical frequency-division multiplexing (DCO-OFDM) modulation includes generating a DCO-OFDM signal with odd-indexed subcarriers carrying data, suppressing even-indexed subcarriers of the DCO-OFDM signal, and transmitting the DCO-OFDM signal via a light source.
(FR) La présente invention concerne un procédé, un système et un dispositif mis en oeuvre par ordinateur pour la modulation par multiplexage par répartition de la fréquence optique polarisé en courant continu (DCO-OFDM)) qui comprend la génération d'un signal DCO-OFDM avec des sous-porteuses à indice impair transportant des données, la suppression de sous-porteuses à indice pair du signal DCO-OFDM, et la transmission du signal DCO-OFDM par l'intermédiaire d'une source de lumière.
