Blind and Fast Modulation Format Identification by Frequency-offset Loading for Hitless Flexible Transceiver

Not Accessible

Your library or personal account may give you access

Abstract

We propose a blind and fast modulation format identification enabled by frequency-offset loading technique for hitless flexible transceiver. Arbitrary format switching among 28-Gbaud DP-4/8/16/64QAM, hybrid-4/16QAM, and SP-128QAM can be accurately identified with only 2048 symbols.
