Abstract
A code-aided iterative carrier phase estimator using selective soft decision feedback is proposed. Based on the reliability metric defined, soft decisions provided by the soft-in/soft-out channel decoder with higher reliabilities are selected to perform carrier phase estimation iteratively. Simulation results demonstrate the performance improvement of the proposed algorithm in both the unbiased estimation range and the estimation precision. The overall bit error rate performance of the coded systems with different phase estimators is also compared.
