Title (EN) CROSS POLARIZATION MODULATION COMPENSATOR
(FR) COMPENSATEUR DE MODULATION DE POLARISATION CROISÉE
Abstract:
(EN) The present invention provides a cross polarization modulation, XPolM, compensator (100) for an optical coherent receiver (300). The XPolM compensator includes a receiving section (101), configured to receive digital input signals (102), a tap coefficient estimation unit (103), configured to determine tap coefficients (103tc) based on sequences (102s) of samples in the digital input signals (102), and a filter section (104), configured to obtain XPolM compensated output signals (105), based on the digital input signals (102) and on the tap coefficients (103tc).
(FR) La présente invention concerne une modulation de polarisation croisée, XPolM, compensateur (100) pour un récepteur optique cohérent (300). Le compensateur XPolM comprend une section de réception (101), configurée pour recevoir des signaux d'entrée numériques (102), une unité d'estimation de coefficient de prise (103), configurée pour déterminer des coefficients de prise (103 tc) sur la base de séquences (102s) d'échantillons dans les signaux d'entrée numériques (102), et une section de filtre (104), configurée pour obtenir des signaux de sortie compensés XPolM (105), sur la base des signaux d'entrée numériques (102) et des coefficients de prise (103tc).
