INITIAL ACQUISITION METHOD OF CDMA FIXED RECEIVER SYSTEM

摘要

PURPOSE: An acquisition method of a CDMA(Code Division Multiple Access) fixed receiving system is provided to quickly obtain an acquisition so as to reduce an acquisition time, and to correctly perform an acquisition. CONSTITUTION: A system selects successive PN(Pseudo Noise) codes of an N number having same off-sets at each period, and acquires a phase difference of a PN code of an M number which is smaller than N. The system successively acquires a next PN code, and acquires a PN code of the N number. The system acquires representative values of the PN codes within a window on the basis of the PN codes of the N number at each period, and decides the representative values as PN code.
