Claim:
1. A method of performing cell search in a wireless communication system, performed by a user equipment, the method comprising: receiving a primary synchronization code (PSC); receiving a first secondary synchronization signal comprising a first sequence and a second sequence; receiving a second secondary synchronization signal comprising the first sequence and the second sequence; and determining a cell identity based on the PSC, the first secondary synchronization signal and the second secondary synchronization signal, wherein the first sequence of the first secondary synchronization signal is scrambled by using a first scrambling code, the second sequence of the first secondary synchronization signal is scrambled by using a second scrambling code, the first sequence of the second secondary synchronization signal is scrambled by using the second scrambling code, and the second sequence of the second secondary synchronization signal is scrambled by using the first scrambling code, wherein the first scrambling code and the second scrambling code are associated with the PSC, and wherein the first and second scrambling codes are defined by m-sequences generated by a generating polynomial x
