Wide-Range and Fast-Convergence Frequency Offset Estimator by BER-Aiding for Optical Coherent Receivers
PADE, a digital frequency offset (FO) estimator for optical coherent receivers, has a wide stable-running estimation range. But it converges correctly only when initialized FO is near to real FO. We present a solution to break the restriction by BER aiding, which is proved to be effective by simulation.
