ABSTRACT:
A method is for decoding a bit stream from a waveform representing the bit stream, having a first synchronization mark, data, and a second synchronization mark. Digitized samples are decoded to form a reconstructed bit stream. The reconstructed bit stream is then stored. At least one of the first synchronization mark and the second synchronization mark are then extracted from the reconstructed bit stream. Finally, the data are extracted from the reconstructed bit stream using an iterative decoding process, in accordance with at least one of the first synchronization mark and the second synchronization mark. As such, loss of the data between the first synchronization mark and the second synchronization mark, if there is a problem with the first synchronization mark, is avoided.
