Title:
【発明の名称】敏速なWCDMA獲得のための方法及び装置
Document Type and Number:
Japanese Patent JP2003503880
Kind Code:
A
Abstract:
A method and apparatus for quickly acquiring synchronization of a signal in WCDMA communication system utilizing variable duration sample accumulation, validity testing of decoder estimates, and parallel decoding of multiple synchronization signals within a PERCH channel. The receiver (204) accumulates the samples necessary to reliably determine slot tuning. Until slot timing estimates pass a validity test, samples are accumulated (304A, 304B) for frame timing estimates. Until frame timing estimates pass a validity test, samples are analyzed to determine the pilot offset of the channel.
