Abstract: A method, communication device, and user equipment (UE) for detecting a synchronization signal in a wireless communication system are provided. The method includes receiving a synchronization signal including a code sequence of length 2N, wherein the code sequence includes an even code sequence of length N and an odd code sequence of length N; obtaining the code sequence by de-scrambling the received synchronization signal; generating and storing a correlation value of the even code sequence by full-correlating the even code sequence with a number of candidate even code sequences; generating a correlation value of the odd code sequence by full-correlating the odd code sequence with a number of candidate odd code sequences, and obtaining a correlation value of the code sequence by adding the stored correlation value of the even code sequence corresponding to the candidate odd code sequences to the generated correlation value of the odd code sequence; and detecting the synchronization signal based on the obtained correlation value of the code sequence.
