RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system that is able to restrain reduction in channel transmission capacity even if there is deviation in the arrangement position of an array antenna.SOLUTION: A radio communication system (1) according to the invention comprises a first radio communication device (100) including a first array antenna and a second radio communication device (200) including a second array antenna, and performs radio communication by MIMO transmission between the first array antenna and the second array antenna. The radio communication system comprises: a transmission path information acquisition unit (108) that obtains the electrical length of a transmission path between an antenna element composing the first array antenna and an antenna element composing the second array antenna; and an optimal frequency calculation unit (109) that functions as a frequency acquisition unit for obtaining a radio frequency used for radio communication between the first radio communication device and the second radio communication device on the basis of the electrical length obtained by the transmission path information acquisition unit.
