A CODE SYNCHRONIZATION UNIT AND METHOD

Title:

A CODE SYNCHRONIZATION UNIT AND METHOD

Document Type and Number:

WIPO Patent Application WO1998044670

Kind Code:

A3

Abstract:

A pilot acquisition unit for code division multiple access (CDMA) communication systems is provided which includes a fast Hadamard transform (FHT) unit and a pre-Hadamard processing unit. The FHT unit determines the quality, in accordance with a metric, of each of a set of possible pseudo-random number (PN) loadings and the pre-Hadamard processing unit generates a vector u per set of PN loadings. The vector u defines a quality metric of a received pilot signal with the set of possible PN loadings, the pre-Hadamard processing unit providing the vector u to the FHT unit.
