Title: Cell search method in wireless communication system

Abstract: Provided is a cell search method in a wireless communication system. According to the cell search method, when detecting SSS in order to search a cell group ID in 3GPP LTE communication, it is possible to reduce the computational complexity for SSS detection by selecting the sequence group of which cross-correlation between initially grouped SSS sequences is a predetermined value or more, computing cross-correlation with the sequences in the selected sequence group, and extracting a cell group ID through detection of the SSS sequence having the highest cross-correlation.
