Bayesian Phase Search for Probabilistic Amplitude Shaping

Published 5 Sep 2023 in eess.SP, cs.IT, and math.IT | (2309.02003v2)

Abstract: We introduce a Bayesian carrier phase recovery (CPR) algorithm which is robust against low signal-to-noise ratio scenarios. It is therefore effective for phase recovery for probabilistic amplitude shaping (PAS). Results validate that the new algorithm overcomes the degradation experienced by blind phase-search CPR for PAS.
