Title: DEVIATION COMPENSATOR
Abstract:
System reliability and communication quality are improved efficiently by compensating for amplitude and phase deflections. First combiner means (11-1) combines undeviated signals (Xn(t)) on transmission paths and generates a first combined signal (r(t)). Second combiner means (11-2) combines deviated signals (Zn(t)) on transmission paths and generates a second combined signal (Y(t)). On the basis of the first combined signal (r(t)), the second combined signal (Y(t)) and the undeviated or deviated signal (Un(t)), calculation means (12) calculates correction values (Wn(t)) for the transmission paths to compensate for deviations. Compensating means (13) dynamically compensates for deviations based on the correction values (Wn(t)).
