From a transmitter to a transmission line, a baseband signal is transmitted together with a replica signal created by superposing the baseband signal onto Carrier Frequency C 1. Similarly, from a transmitter to a transmission line, a baseband signal is transmitted together with a replica signal created by superposing the baseband signal onto Carrier Frequency C 2. At a receiver, the receive signal is branched into two. From one of the branched signals, the baseband signal is extracted by passing the signal through a filter. From the remaining signal, the replica signal on Carrier Frequency C 2 is converted into the baseband, which is also extracted. The resultant signals are input to an adaptive equalizer. The output signal from the adaptive equalizer now has the same waveform as the crosstalk signal that has crossed into the baseband signal. The crosstalk can be suppressed by subtracting these two signals from each other by use of a subtracter.
