Variation compensating unit
First Claim
1. A variation compensating unit for compensating variation including at least one of an amplitude variation and phase variation which will occur in the case of transmitting signals via transmission paths, the unit comprising:
- a first combining section for generating a first combined signal by combining signals on different transmission paths in which the variation has not occurred;
a second combining section for generating a second combined signal by combining signals on the different transmission paths in which the variation has occurred;
a compensation value calculating section for calculating compensation values for compensating the variation according to the transmission paths on the basis of the first combined signal, the second combined signal, and the signals on the different transmission paths in which the variation has not occurred or in which the variation has occurred; and
a compensating section for compensating the variation dynamically on the basis of the compensation values.

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.
