FIELD: radio engineering.
SUBSTANCE: proposed method and device designed for fast synchronization of signal in wade-band code-division multiple access (WCDMA) system involve use of accumulations of variable-length samples, testing of decoder estimates for reliability, and concurrent decoding of plurality of sync signals in PERCH channel. Receiver accumulates samples required for reliable estimation of time interval synchronization. As long as time interval synchronization estimates have not passed reliability tests, samples are accumulated for frame synchronization estimates. As long as frame synchronization estimates have not passed reliability tests, samples are analyzed to determine channel pilot signal shift.
EFFECT: reduced time for pulling into synchronism.
