Abstract :
A Monte Carlo integration based method to calculate symbol log-likelihood ratios for soft iterative decoding in the presence of imperfect carrier phase estimation (CPE) is proposed. The proposed method shows good robustness when CPE is imperfect, in particular for optimum modulation schemes.
