CELL SEARCHER OF MOBILE TERMINAL AND NEIGHBOR CELL SEARCHING METHOD THEREOF

摘要

PURPOSE: A cell searcher of a portable terminal and adjacent cell search method are provided to reduce the probability of misdetection by removing PSS(Primary Synchronization Signal) symbols of a home cell in a time domain. CONSTITUTION: A cell searcher of a portable terminal executes initial cell search operation(S110). When PSS codes of a home cell are corresponded to the PSS codes of adjacent cells, a time domain home cell remover of the cell searcher removes PSS symbols for the home cell from signals outputted from a decimator in a time domain(S120,S130). When the PSS codes are not corresponded to the PSS codes of the adjacent cells, a PSS code detector and an SSS(Secondary Synchronization Signal) code detector respectively receive the signals. The detectors detect the adjacent cells through cross-correlation operation(S140).
