ABSTRACT:
A method slot and frame synchronization of in a wireless system, the method includes: processing samples and a pair of primary synchronization code forming sequences by a pair of serially coupled filters to provide primary results; finding, in response to the primary results, slots boundaries; processing selected samples and multiple pairs of secondary synchronization code forming sequences by at least a second filter of the pair of serially coupled filters to provide secondary results; wherein the selected samples correspond to the slots boundaries; and detecting secondary synchronization sequences included in a frame in response to the secondary results.
