Abstract
Methods and apparatuses for dynamically adjusting sync windows are described. A default sync window is set; a data signal is input; detecting if parts of the data signal within the sync window form a sync pattern; accumulating a count of the sync pattern within and without the sync window; and reducing the sync window when the count of sync pattern within the sync window achieves a first threshold value, and increasing the sync window when the count of the sync pattern outside the sync window achieves a second threshold value.
