Abstract: PROBLEM TO BE SOLVED: To provide a signal compensation device which is capable of extracting a desired wave free from the influence of nonlinear distortion of a signal amplifier.
SOLUTION: A signal compensation device 8 is used for a communication system wherein a superposition signal wherein an IB signal transmitted from a first station and an OB signal different from the IB signal, which is transmitted from a second station, are superposed one over the other is transmitted to the second station from a relay station including TWTA, and the signal compensation device inputs a replica signal being a replica of the OB signal, to a nonlinear compensation model wherein input/output characteristics of an output signal to an input signal show input/output characteristics of TWTA including a linear region and a nonlinear region, to generate a compensated replica signal. Therefore, signal deterioration of the desired wave (the IB signal) is considerably reduced by the signal compensation device 8. The signal compensation device 8 is applicable to an unnecessary wave demodulation system as well as a delay detection system.
