Doubly-Differential Coherent 100G Transmission: Multi-Symbol Decision-Directed Carrier Phase Estimation with Intradyne Frequency Offset Cancellation

Not Accessible

Your library or personal account may give you access

Abstract

The proposed novel carrier phase and frequency recovery system automatically cancels LO frequency offsets, outperforming conventional schemes in mean square phase error, with low complexity linear processing, using a low number of complex-multiply-adds.
