ABSTRACT:
A multi-antenna system comprising a plurality of linearly connected antenna units, and a base station device connected to at least one of the antenna units. The antenna units connected in a first direction or a second direction are combined to constitute a multi antenna. The multi-antenna system comprises a unit addition unit that adds one unit to number-of-connected-antenna-units information which is input from the first direction; a number-of-connections sending unit that sends the number-of-connected-antenna-units information, to which one unit has been added as described above, as the number-of-connected-antenna-units information in the second direction; a received data addition unit that adds input digital data, which is input from the first direction, to received digital data; an added-digital-data sending unit that sends the digital data, to which input digital data has been added, as input digital data in the second direction; and a transmission data sending unit that copies the transmission digital data, which is input from the second direction, and sends the copied digital data in the first direction.
