FSK無線機を用いる偏波制御通信システム

抄録

The wireless system selecting polarization on which information signal is transferred to achieve better communication quality is proposed. The system uses a radio device that consists of a micro controller, two RF chips, a 90 degree hybrid coupler, and two perpendicular antennas to generate the rotating polarization wave where these RF chips are operated at the different local frequencies. Since the proposed system is compatibly operated with the conventional system that uses the same RF chip, it achieves a better quality by selecting both transmitting and receiving polarizations than the conventional system even if a mobile object is passing the radio devices or carrying it.
