<P>PROBLEM TO BE SOLVED: To provide a transmission/reception system which can obtain a signal at a stable level from a transmitter, and can prevent a deterioration of a receiving signal. <P>SOLUTION: This transmission/reception system includes: a transmitting side filter 12 for adding characteristics corresponding to a transmitting side tap coefficient to a transmitting signal which is input into a transmitter 1 and is modulated; a receiving side filter 24 for adding characteristics corresponding to a receiving side tap coefficient to the transmitting signal which is sent out from the transmitting side filter 12 and transmitted with an optical transmission line 3 received to a receiver 2; a transmission line characteristics computing part 4 for computing transmission line characteristics of the optical transmission line 3; and a tap coefficient computing part 5 for computing the transmitting side tap coefficient and the receiving side tap coefficient. The tap coefficient computing part 5 combines the transmission line characteristics with an additional characteristics set in response to the transmission line characteristics to compute a composite characteristics, computes the transmitting side tap coefficient based on reverse characteristics of the composite characteristics, and also computes the receiving side tap coefficient based on the additional characteristics. <P>COPYRIGHT: (C)2009,JPO&INPIT |
