Blind Optical Modulation Format Identification From Physical Layer Characteristics [PDF]

open access: yesJournal of Lightwave Technology, 2014
We describe and experimentally demonstrate automated identification of optical modulation formats exclusively from physical-layer signal characteristics. The system identifies the data encoding as on-off keyed versus binary or quadrature phase-shift keyed, as well as auxiliary modulation profiles.

Blind modulation format identification for digital coherent receivers

open access: yesOptics Express, 2015
In this paper, a simple novel digital modulation format identification (MFI) scheme for coherent optical systems is proposed. The scheme is based on the evaluation of the peak-to-average-power ratio (PAPR) of the incoming data samples after analog-to-digital conversion (ADC), chromatic dispersion (CD) and polarization mode demultiplexing (PMD ...

Modulation format identification aided hitless flexible coherent transceiver

open access: yesOptics Express, 2016
We propose a hitless flexible coherent transceiver enabled by a novel modulation format identification (MFI) scheme for dynamic agile optical networks. The modulation format transparent digital signal processing (DSP) is realized by a block-wise decision-directed least-mean-square (DD-LMS) equalizer for channel tracking, and a pilot symbol aided ...
