PROBLEM TO BE SOLVED: To provide the synchronization device preparing plural antennas, estimating a desired wave and an interference wave independently from reception signals obtained from the plural antennas and selecting the reception signal with high power and less effect of fading. SOLUTION: The synchronization device is provided with two antennas 106, 113, two fading estimate devices 1105, 112, correlation devices 101, 103 in pairs, correlation devices 108, 103 in other pairs, two comparators 107, 114, and a synchronization discrimination circuit 115. The fading estimate device estimates a desire wave and an interference wave from reception signals from each antenna and the comparators 107, 114 are used to select a reception signal not affected by fading and with not reduced power and the signal is outputted and given to the synchronization discrimination circuit 115, in which the synchronization is discriminated and then the synchronization is locked at a high speed accurately. |
