Abstract
A variation compensating unit that compensates an amplitude variation and phase variation efficiently and that improves system reliability and communication quality. A first combining section generates a first combined signal by combining signal on different transmission paths in which a variation has not occurred. A second combining section generates a second combined signal by combining signal on the different transmission paths in which a variation has occurred. A compensation value calculating section calculates compensation values for compensating variation according to the transmission paths on the basis of the first combined signal, the second combined signal, and signal on each transmission path in which a variation has not occurred or in which a variation has occurred. A compensating section compensates variation dynamically on the basis of the compensation values.
