A communication quality test is performed for combinations between antenna setting candidates of a transmitting antenna of a first communication device (1) and a receiving antenna of a second communication device (2), and a list in which antenna-setting pairs are arranged according to the communication quality is created. If there are two or more antenna-setting pairs having the same antenna setting for one of the transmitting and receiving antennas, it is determined that an antenna-setting pair(s) ranked in a second or lower place is caused by a side-lobe and thus the list is updated by deleting that antenna-setting pair(s) from the list or lowering its priority rank in the list. The above-described steps are performed for a receiving antenna of the first communication device (1) and a transmitting antenna of the second communication device (2). An antenna-setting pair is successively selected from the updated antenna-setting-pair list and communication is performed. |
