Abstract:
1. An apparatus, comprising: a searcher for correlating a received signal with synchronization sequence to produce a first plurality of search results, each search result comprising at least one of an energy indicator or an offset; a processor for comparing a stored offset from a previous search with the offset of a search result of the first plurality of search results and removing the corresponding search result from the first plurality of search results when the search result offset is within a first predetermined threshold of the stored offset; a memory for storing a first plurality of scrambling code identifiers and associated offsets, the stored offset selected there from; wherein the memory further stores a second plurality of scrambling code identifiers; wherein the searcher further correlates the received signal with a scrambling code over a search window to produce a list search result; wherein the processor further directs the searcher to search a search window around the offset associated with one or more of the first plurality of search results using one or more scrambling codes identified by one or more of the second plurality of scrambling code identifiers, respectively; and wherein the processor further removes a scrambling code identifier from the second plurality of code identifiers when the list search result exceeds a second predetermined threshold.
