An external signal is received by the first wireless transmission device of one wireless transmission device group, and then is divided. One divided signal is transmitted to the first wireless transmission device of the other wireless transmission device group opposite to the one wireless transmission device group, and the other divided signal is transmitted to the second wireless transmission device of the one wireless transmission device group. In the same manner, in the second, third, . . . , wireless transmission devices of the one wireless transmission device group, an input signal is divided into two signals, and the divided signals are each transmitted to the opposing wireless transmission device of the other wireless transmission device group and to the adjacent wireless transmission device of the one wireless transmission device group. The wireless transmission devices of the other wireless transmission device group each extracts a signal from the wireless signal transmitted from the opposing wireless transmission device of the one wireless transmission device group, and transmits the signal to the preceding adjacent wireless transmission device of the other wireless transmission device group. The first wireless transmission devices of the other wireless transmission device group combines a signal extracted from the wireless signal transmitted from the first wireless transmission device of the one wireless transmission device group and a signal transmitted from the second wireless transmission device of the other wireless transmission device group together, and outputs the combined signal to the outside. |
