Patent ID: 7194011

Claim:
For use in a receiver, a pipelined apparatus for performing cell searches comprising: a primary search stage receiving a primary synchronization channel (P-SCH) signal and detecting therein a first maximum peak associated with a slot boundary in said P-SCH signal, wherein said primary search stage generates slot timing data from said first maximum peak; a secondary search stage receiving a secondary synchronization channel (S-SCH) signal and said slot timing data from said primary search stage and detecting in said S-SCH signal a second maximum peak associated with a frame boundary, wherein said secondary search stage generates from said frame boundary and said slot timing data frame timing data and a group ID of a base station transmitting said P-SCH signal and said S-SCH signal; and a Gold code search stage receiving i) a common control pilot channel (CPICH) signal, ii) said slot timing data from said primary search stage, and iii) said frame timing data and said group ID from said secondary search stage and detecting in said CPICH signal a third maximum peak associated with a Gold code of said base station.
