This letter considers carrier phase recovery in turbo receivers. Firstly, a novel maximum-likelihood (ML) based iterative carrier phase estimator is proposed for coded linear modulations over static phase channels. The proposed carrier phase estimator, combined with the iterative sum-product decoder, performs very close to the Cramer-Rao bound. Moreover, for practical dynamics phase channels, an efficient carrier phase recovery method is proposed to perfom very close to that of a perfect coherent receiver.
