METHOD AND APPARATUS FOR DETECTION OF PILOT SIGNAL WITH FREQUENCY OFFSET USING MULTI-STAGE CORRELATOR

Title:

METHOD AND APPARATUS FOR DETECTION OF PILOT SIGNAL WITH FREQUENCY OFFSET USING MULTI-STAGE CORRELATOR

Document Type and Number:

WIPO Patent Application WO2005002314

Kind Code:

A3

Abstract:

The disclosed embodiments relate to a method and apparatus for performing a pilot synchronization operation in a wireless communication system. The system may contain a plurality of sliding correlators (102, 106, 110, 114) that each receives a portion of a received correlation sequence and provides a partial correlation output. An absolute value block (118-124) may take the absolute value of each partial correlation output. Circuitry (126) may combine the absolute values of each of the partial correlation outputs to form a correlation output.
