<P>PROBLEM TO BE SOLVED: To reduce the complexity of a structure or a method for compensating nonlinearity of a communication system. <P>SOLUTION: A nonlinear compensation device has: an information acquisition unit acquiring a symbol information sequence of an input pulse signal on a transmission side of a communication system; a perturbation amount calculation unit calculating a weighting sum of pulse interactions among a plurality of items at a plurality of different times to the current time, and acquiring a perturbation amount generated by a nonlinear effect at the current time on a transmission link; and an information compensation unit acquiring the symbol information sequence in which the nonlinearity is reduced at the current time, based on a difference between the symbol information sequence at the current time acquired by the information acquisition unit and the perturbation amount acquired by the perturbation amount calculation unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
