Mimo communication system having deterministic communication path and antenna arrangement method therfor

Abstract

A MIMO communication system has deterministic channels between the transmission side where a plurality of transmission antennas are arranged and the reception side where a plurality of reception antennas are arranged and used in a line-of-sight environment. The system includes channel matrix calculation processing means for calculating a channel matrix for constructing orthogonal channels as the channel on a transmission or reception side or both of the transmission and reception sides. The plurality of transmission antennas and plurality of reception antennas constituting the channel matrix are horizontally arranged with respect to the ground.
