FIELD: mobile communication systems. SUBSTANCE: device has at least two PREUDORANDOMNESS NOISE (PRN)-sequence phase selectors used to search for PRN-sequence phase of at least two different input band signals using different assigned search conditions and to yield data on PRN phase and energy. Controller functions to assign different search conditions to PRN-sequence phase selectors and to determine minimal phase change period using data on PRN phase and energy received from PRN-sequence phase selectors. EFFECT: reduced phase search time. 20 cl, 11 dwg
