<p><P>PROBLEM TO BE SOLVED: To provide a transmission/reception system in which a crosstalk mixed in a receiver is detected to effectively suppress the influence of the crosstalk without wiring connection with a neighboring transmitter. <P>SOLUTION: A replica signal wherein a baseband signal is put on a carrier frequency C1 out of the band, is sent from a transmitter 10-1 to a transmission line 20-1 in addition to the baseband signal, and the baseband signal and the replica signal of a carrier frequency C2 are similarly sent from a transmitter 10-1 to the transmission line. In a receiver 30-1, a received signal is branched into two signals, one of them is passed through a filter to extract a baseband signal, and the replica signal of the carrier frequency C2 is converted into a baseband and extracted from the remaining signal and then inputted to an adaptive equalizer 33-1. The output signal of the adaptive equalizer 33-1 has the same waveform as a crosstalk mixed in the baseband signal and the both are subtracted by a subtracter to suppress the crosstalk. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
