Title: RADIO COMMUNICATION SYSTEM, TRANSMITTING DEVICE, AND COMMUNICATION METHOD
Abstract:
A radio communication system (1) is provided with a transmitting device (10) which transmits a radio signal and a receiving device (20) which receives the radio signal. The transmitting device (10) is provided with: a plurality of antennas (120) which respectively emit a plurality of linearly polarized waves of which directions of polarization are different from one another; and a control unit (111) which sequentially uses a plurality of different sets of the antennas (120) and frequencies. The use of each of the sets comprises transmitting the radio signal by using the antenna (120) included in the set and by using, as a carrier wave frequency for the radio signal, the frequency included in the set. Each of the plurality of sets is formed by selecting an antenna (120) for the set from among the plurality of antennas (120) and by selecting a frequency for the set from among the plurality of frequencies included in a frequency group corresponding to the antenna (120) for the set.
