RADIO COMMUNICATION APPARATUS AND SYSTEM

PROBLEM TO BE SOLVED: To provide a radio communication apparatus which reduces interference due to electric waves transmitted from other systems. SOLUTION: According to a first embodiment, the radio communication apparatus is provided. The radio communication apparatus includes a vertical polarization antenna, a horizontal polarization antenna, a receiving-side phase rotation unit configured to rotate phases of signals received by the vertical polarization antenna and the horizontal polarization antenna, and a maximum power detector configured to inspect a phase associated with a maximum power of the received signals having the maximum power and to provide the receiving-side phase rotation unit with the phase associated with the maximum power. The receiving-side phase rotation unit rotates the phase of the received signals by the phase associated with the maximum power, which is received from the maximum power detector.
