Abstract:
1. A relay station apparatus provided in a plurality of propagation paths between a transmission apparatus and a reception apparatus in a diversity technique to relay an error correction coded signal from the transmission apparatus to the reception apparatus, the relay station apparatus comprising: a monitoring section which monitors the error correction coded signal from the transmission apparatus through a first propagation path between the relay station and the transmission apparatus, and monitors a first relay signal that is transmitted by another relay station apparatus that relays the error correction coded signal from the transmission apparatus to the reception apparatus, through a second propagation path different from the first propagation path; an error detecting section which detects an error in the received first relay signal; a hard deciding section which makes a hard decision of the received first relay signal; an error position information generating section which generates error position information based on an error detection result and a hard decision result; a signal generating section which generates a second relay signal by adding the generated error position information to the received error correction coded signal from the transmission apparatus; and a transmitting section which transmits the generated second relay signal to the reception apparatus.
