Interplay of Probabilistic Shaping and Carrier Phase Recovery for Nonlinearity Mitigation (2009.01135v1)
Published 2 Sep 2020 in cs.IT and math.IT
Abstract: The interaction between carrier phase recovery and probabilistic amplitude shaping (PAS) in the nonlinear regime is investigated. We show that, for sufficiently high signal-to-noise ratio, the first provides the same inter-channel nonlinearity mitigation achieved by short block-length PAS.
