摘要: A bit clock recovery apparatus for digital storage readout employing sync frames, where an oversampled readout signal is stored in memory, sync patterns are located in the signal using DSP means, distances of consecutive sync pattern locations are calculated, and bit clock is recovered from these distances and the knowledge about the data framing structure.

摘要: The error correction capability of block codes can be doubled if error locations are known. Prior art approaches for error location detection always involve adding dedicated redundant data which then are evaluated to yield error location information. The present invention proposes and describes how error location information in the form of clues (31) is derived from given DC control bits (32) that are anyway present in a data stream.
