<p>A variation compensating unit that compensates an amplitude variation and phase variation efficiently and that improves system reliability and communication quality. First combining means (11-1) generates a first combined signal (r(t)) by combining signal (Xn(t)) on different transmission paths in which a variation has not occurred. Second combining means (11-2) generates a second combined signal (Y(t)) by combining signal (Zn(t)) on the different transmission paths in which a variation has occurred. Compensation value calculating means (12) calculates compensation values (Wn(t)) for compensating variation according to the transmission paths on the basis of the first combined signal (r(t)), the second combined signal (Y(t)), and signal Un(t) on each transmission path in which a variation has not occurred or in which a variation has occurred. Compensating means (13) compensates variation dynamically on the basis of the compensation values (Wn(t)). <IMAGE></p> |
