ABSTRACT:
Provided is a mobile communication system capable of obtaining a diversity effect even when a signal received by a relay station has an error in a corporate relay to which time space encoding is applied. In this mobile communication system, when S1has no error and S2has an error, a relay station (1) does not perform relay transmission at time t (Null) and relay-transmits S1* to a base station at time t+T. That is, in this case, the relay station (1) relay-transmits at time t+T only S1to be transmitted at time t when no error is contained in either S1or S2. Moreover, when S1has an error and S2has no error, the relay station (1) relay-transmits S2at time t and does not perform relay transmission at time t+T (Null). That is, in this case, the relay station (1) relay-transmits only S2to be transmitted at time t+T at time t if no error is contained in either S1or S2.
