摘要
PURPOSE: A method for deciding priority of PN code mask vectors and a method for obtaining PN code synchronization using the same in a CDMA method are provided to reduce average time for obtaining PN code by arranging priority to mask vectors according to the order recently used. CONSTITUTION: PN code mask vectors of a base station recently connected are established as m number of priority mask vectors(33). A mask vector corresponding to the PN code obtained from the recent connection(31) and the existing priority mask vectors(33) are compared and searched(32). If the same mask vector does not exist, the mask vector corresponding to the PN code obtained from the recent connection(31) is stored as the first one of the priority mask vectors and the lowest priority mask vector is stored at the mask vector of the existing method(34) eliminating the mask vector corresponding to the PN code obtained from the recent connection(31) from the mask vector of the existing method(34). If the same mask vector exists, the mask vector corresponding to the PN code obtained from the recent connection(31) are discarded(35).
