Decision-Aided Carrier Phase Estimation for Coherent Optical Communications
TL;DR: In this article, an adaptive decision-aided (DA) receiver that does not require knowledge of the statistical characteristics of the carrier phase, or any parameter to be preset, is proposed.

Optimal and Approximate Methods for Detection of Uncoded Data with Carrier Phase Noise
TL;DR: It is shown that the ML detector for this problem can be formulated as a weighted sum of central moments of the conditional PDF of phase noise, and this new optimal structure is tractable with respect to the previously known optimal ML receiver.

Adaptive Maximum Likelihood Sequence Detection for QPSK Coherent Optical Communication System
TL;DR: A novel Viterbi-type adaptive maximum likelihood sequence detection algorithm that can self-adjust the effective memory length of the phase estimator and automatically deliver the optimum bit-error rate performance without requiring any prior statistical knowledge of the optical channel.

Per-Survivor Processing: a general approach to MLSE in uncertain environments
TL;DR: Per-survivor processing (PSP) provides a general framework for the approximation of maximum likelihood sequence estimation (MLSE) algorithms whenever the presence of unknown quantities prevents the precise use of the classical Viterbi algorithm.

Coherent detection of optical quadrature phase-shift keying signals with carrier phase estimation
TL;DR: In this paper, a coherent optical receiver for demodulating optical quadrature phase-shift keying (QPSK) signals is proposed. But the authors do not consider the phase-diversity homodyne detection at the receiver.
