Abstract
Provided is a MIMO communication device which can maintain the MIMO communication characteristic at a certain level regardless of the device installation position. The MIMO communication device () includes antenna elements (--) as a first and a second antenna element which are arranged on a single straight line and an antenna element (-) or an antenna element (-) as a third antenna element which is arranged out of the straight line. A MIMO modulation unit () is connected to all the antenna elements. This assures that there exists a combination of antennas having other than 0 as a matrix expression of a channel estimation matrix in a propagation path between the MIMO communication device () and the communication partner regardless of the installation position of the MIMO communication device () with respect to a communication partner. As a result, it is possible to realize the MIMO communication device which can maintain the MIMO communication characteristic at a certain level or above regardless of the device installation position.
