摘要
Methods and apparatus are provided for detection of a synchronization mark based on a position of an extreme distance metric. A synchronization mark is detected in a received signal by computing a distance metric between the received signal and an ideal version of the received signal expected when reading the synchronization mark, wherein the distance metric is computed for a plurality of positions within a search window; determining a substantially extreme distance metric within the search window; and detecting the synchronization mark based on a position of the substantially extreme distance metric. The distance metric can comprise a sum of square differences or a Euclidean distance between the received signal and the ideal version of the received signal.
