Abstract—In a CDMA cellular system, the process of the
mobile station searching for a cell and achieving code and time
synchronization to its downlink scrambling code is referred to
as cell search. Cell search is performed in three scenarios: initial
cell search when a mobile station is switched on, idle mode search
when inactive, and active mode search during a call. The latter
two are also called target cell search. This paper presents algorithms
and results for both initial and target cell search scenarios
for the Wideband CDMA (W-CDMA) standard. In W-CDMA,
the cell search itself is divided into five acquisition stages: slot
synchronization, frame synchronization and scrambling code
group identification, scrambling code identification, frequency
acquisition, and cell identification. Initial cell search needs all five
stages, while target cell search in general does not need the last
two stages.
