<P>PROBLEM TO BE SOLVED: To provide a radio relay apparatus capable of canceling a loop interference wave in MIMO communication. <P>SOLUTION: A radio relay apparatus 500 comprises: a cancel part 110 obtaining M second base band signals by canceling each of M simulation signals simulating loop interference waves at M reception antennas 101-1 to 101-M from each of M first base band signals; a weight calculation part 220 calculating M×M weight corresponding to M×M propagation paths through which each of the M second base band signals loops around each of the M reception antennas 101-1 to 101-M; and a weight multiplication part 130 obtaining each of the M simulation signals to be supplied to the cancel part 110, by multiplying the M second base band signals by M weight corresponding to each of the M reception antennas 101-1 to 101-M and synthesizing them. <P>COPYRIGHT: (C)2012,JPO&INPIT |
