Title:
RECEPTION SIGNAL PROCESSING DEVICE, RECEPTION SIGNAL PROCESSING METHOD, AND OPTICAL RECEIVER
Document Type and Number:
WIPO Patent Application WO/2020/174656
Kind Code:
A1
Abstract:
This reception signal processing device (43) is configured to be provided with: a Bayesian estimation unit (47) which, using a Kalman filter, performs Bayesian estimation on phase noise in a polarized wave signal indicative of the polarized wave state of a reception signal that has a symbol time series superimposed thereon and which, using a phase noise estimate, removes the phase noise contained in the polarized wave signal; and a weight update unit (48) which, when the Bayesian estimation unit (47) performs Bayesian estimation on phase noise, accumulates phase noise estimates, and causes the Bayesian estimation unit (47) to update a Kalman gain of the Kalman filter on the basis of the accumulated estimates.
