    Abstract: A method of detecting and correcting cycle slip in a data stream including sync symbol blocks and data symbol blocks prior to feedback carrier recovery is described. A phase ambiguity angle is computed upon detecting a last sync symbol of a sync symbol block in the data stream. A cycle slip corrector initiates cycle slip correction upon determining the computed phase ambiguity angle is different from a previous computed phase ambiguity angle to generate a corrected data stream. The corrected data stream is provided to a feedback carrier recovery circuit.

    Abstract: The present invention relates to an arrangement for adaptive bit recovery, and to an apparatus for reading from and/or writing to recording media using such arrangement. According to the invention, an arrangement for adaptive bit recovery including an adaptive equalizer (13) and an adaptive partial response maximum likelihood detector (14) further includes an overflow control block (86) for the adaptive equalizer (13) for monitoring one or more of the adaptation coefficients and/or a state violation checker (162) for monitoring the allowed states and indicating state violations as well as and a noise detector (155) for detecting larger deviations of the target values.
