RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system capable of achieving stable MIMO communication, if a transmission path of a disabled state occurs in multi-user MIMO communication.

SOLUTION: In a radio transmission device 1000, a control unit 50 calculates a weight coefficient to a transmission signal for MIMO transmission, based on channel status information from the reception side. A faulty antenna detection unit 82 detects a faulty antenna from the channel status information. A channel information repair processing unit 84 repairs an element corresponding to the faulty antenna among matrix elements of the channel status information corresponding to a transmission path matrix fed back from the receiver side, so as to supply to the control unit 50.
