A method for transmitting a synchronization channel using multi-antenna is disclosed. In a method for transmitting a synchronization channel for using a synchronization channel as a phase reference when decoding a broadcast channel, the method includes using a pre-decided shift value for each antenna, wherein the shift value is pre-decided with a user equipment, so as to apply circular shifts to sequences of the synchronization channel, and transmitting the sequences having the circular shifts applied thereto from a base station to the user equipment. Herein, space frequency/time block codes (SFBC/STBC) may be applied to the broadcast channel. In performing time/frequency domain synchronization in the synchronization channel, regardless of the number of transmission antennae used by the base station when transmitting signals, the synchronization process may be performed. Also, multi-antenna gain may be obtained when transmitting the synchronization channel. Furthermore, channel estimation may be performed for each antenna, and by applying transmission diversity methods to the BCH/control channel/data channel and so on, the performance of the present invention may also be enhanced.
