The main contributions of the paper are i the development of a Monte Carlo framework for phase noise estimation with special attention to sequential importance sampling and Rao-Blackwellization ii the interpretation of existing Monte Carlo solutions within this generic framework and iii the derivation of a novel phase noise estimator. Contrary to the ad hoc phase noise estimators that have been proposed in the past the estimators considered in this paper are derived from solid probabilistic and performance-determining arguments. Computer simulations demonstrate that on one hand the Monte Carlo phase noise estimators outperform the existing estimators and on the other hand our newly proposed solution exhibits a lower complexity than the existing Monte Carlo solutions.
