APPARATUS AND METHOD OF SEARCHING FOR PN SEQUENCE PHASE IN MULTI-CARRIER CDMA MOBILE COMMUNICATION SYSTEM

摘要

A PN sequence phase searching apparatus in a multi-carrier CDMA mobile communication system. At least two PN sequence phase searchers search for th e PN sequence phase of one of at least two different band input signals on different assigned search conditions and output PN phase and energy information. A controller assigns the different search conditions to the PN sequence phase searchers and determines a minimum phase variation period bas ed on the PN phase and energy information received from the PN sequence phase searchers.
