Abstract

A maximum likelihood-based code-aided joint carrier phase estimation and ambiguity resolution algorithm is proposed for coded amplitude and phase shift keying (APSK) signals. The proposed estimator iteratively uses the a posteriori probability of coded bits obtained from the channel decoder to improve the performance of phase estimation and ambiguity resolution. Two initialization schemes are employed for systems with and without pilot symbols, which reduce the number of initial phase values required to bootstrap the iterative estimation algorithm. Compared with the existing estimators, simulation results demonstrate the performance improvement of the proposed algorithm in both mean-squared estimation error and bit error rate with lower computational complexity.
