DEVICE AND METHOD FOR ADAPTIVE COMPENSATION OF DISTORTION AND RESTORATION OF CARRIER SIGNAL FOR COHERENT RECEIVERS Russian patent published in 2018 - IPC H03C3/00 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication. This method for adaptively compensating for the distortions of a received signal, recovering polarization, frequency and carrier phase recovery and eliminating the slippage of the phase of the received signal includes using a plurality of reference rings for adaptive distortion compensation of the received signal, restoration of the polarization and breaking of the signal into groups, each of which is located on a circle of different radius; usage of the resulting signal groups to reconstruct the carrier phase; elimination of the phase slippage in the reconstructed carrier phase.

EFFECT: technical result is to eliminate the phenomenon of slippage of the cycle to improve the performance of coherent signal reception devices.
