Patent ID: 7813735

Claim:
A method of performing a cell search comprising: storing a cell identification list of prioritized cell identities (IDs) in a memory; converting the received signal to a baseband signal; selecting a primary synchronization code (PSC) correlation peak location on the baseband signal; determining a first common pilot channel (CPICH) correlation value by using non-coherent integration to correlate a first local signal, created based on a first cell identity (ID) on the cell identification list to the baseband signal; determining whether the first CPICH correlation value is greater than a noise threshold, thus indicating that the first cell ID is a newly found cell ID, or whether a last cell ID in the cell identification list is reached; on a condition that the first CPICH correlation value is determined not to be greater than the noise threshold, determining a second CPICH correlation value by using non-coherent integration to correlate a second local signal to the baseband signal, based on a second cell ID on the cell identification list; and on a condition that the first CPICH correlation value is determined to be greater than the noise threshold or that the last cell ID on the cell identification list is reached, determining whether there is more than one cell ID on the cell identification list having the same timing.
