ABSTRACT:
In order to restore synchronization quickly in the case where synchronization with a transmission signal is not established, when a synchronization signal is not received by an antenna selected in advance in a receiving apparatus (2), a selection controller (C2) continuously switches between antennas (6ato6h), repeats an antenna switching process for measuring received strengths of the respective antennas in a cycle shorter than a transmission period of transmission information in a radio signal so as to detect an antenna with maximum strength, selects and switches to the detected antenna with maximum strength as a receiving antenna for receiving synchronization information, and continues the connection until at least the synchronization information is received. Further, the selection controller (C2) makes a control so that the antenna switching process for detecting the antenna with maximum strength is repeated for a period longer than a non-transmission period of transmission information.
