Abstract:
1. A communication system in which a signal is transferred, comprising: a transmitter that transmits a signal; a receiver that receives a signal transmitted thereto; and an adaptive equalizer that generates a compensated signal by compensating degradation of the signal to be received by the receiver, the adaptive equalizer including: wherein the communication system operates in (i) an actual operating mode in which a data signal to transmit is transferred and (ii) a calibration mode in which an adjusting signal for calibration is transferred, and the adjusting section adjusts the characteristic of the signal compensating section in both of the actual operating and calibration modes, in such a manner as to satisfy a condition that a variation in the characteristic of the signal compensating section is controlled to be smaller over a unit time when the communication system operates in the actual operating mode than when the communication system operates in the calibration mode.
