Patent ID: 8571125

Claim:
A Multiple-Input/Multiple-Output (MIMO) communication system having deterministic channels between a transmission side where a plurality of transmission antennas are arranged and a reception side where a plurality of reception antennas are arranged and used in a line-of-sight environment, the system comprising a channel matrix calculation processing unit for calculating a channel matrix for constructing orthogonal channels as a channel on a transmission or reception side or both of the transmission and reception sides, wherein the plurality of transmission antennas and the plurality of reception antennas constituting the channel matrix are vertically arranged with respect to the ground in each of the transmission and reception sides, and an antenna height of an antenna arranged at a lowest position in each side from the ground is made to be an integral multiple of an antenna interval, the antenna interval being an interval between adjacent antennas in each side and being common in each side and to both sides.
