Cell Search in W-CDMA

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
