Abstract
A mobile wireless communications device and methods therefore, including receiving a signal (710), storing a portion of the received signal (730), identifying all possible pilot signals by determining slot boundary information for the stored signal portion (720), determining frame boundary information and/or scrambling code information (760) of the stored signal portion by correlating the stored signal portion with the scrambling codes based on the slot boundary information. In other embodiments, the search is performed in real-time without storing the signal.
