In a remote unit of a wireless communication system, the speed of
acquisition, or reacquisition, of a pilot signal by a search engine is
increased. PN space is divided into segments and a coarse search of each
segment is performed using a set of "fast" search parameters. A set of
peak signal strengths along with their corresponding PN offsets, is saved
for each segment of PN space. Following the search of all segments of PN
space, the peak signal strengths which were saved during the coarse
acquisition are evaluated. Coarse acquisition search results are used by
the remote unit to determine fine search window parameters for subsequent
searches performed by the remote unit search engine. The fine search
parameters concentrate searching efforts on portions of PN space most
likely to contain a viable base station pilot signal.
