Title:
RADIO COMMUNICATION SYSTEM, RECEIVING DEVICE, CORRECTION DEVICE, ANTENNA CORRECTION METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/213219
Kind Code:
A1
Abstract:
A radio communication system is provided which reduces the number of signals that need to be sent and received to correct an antenna axis. This radio communication system is provided with a transmission device corresponding to OAM radio communication, a receiving device corresponding to OAM radio communication, and a correction device. The correction device corrects the antenna axis of the transmission device and the receiving device on the basis of correlation information which associates: information relating to the antenna of the transmission device and the receiving device; and an inter-mode interference pattern that characterizes interference by a transmission mode when the transmission device transmits a signal on a receiving mode when the receiving device receives a signal.
