PROBLEM TO BE SOLVED: To reduce influence of noise added by FFE without requiring an added component.SOLUTION: In S1, a tap coefficient is acquired so that a training signal before transmission and an output signal are similar by using a tap coefficient matrix W, an output signal matrix Y and a delay matrix U. In S2, the tap coefficient acquired in the S1 is set and the training signal before transmission is compared with the output signal to acquire a sub peak. In S3, whether the set tap coefficient can be received or not is determined. A step (S4) for inserting a row corresponding to the sub peak into the output signal matrix Y and the delay matrix U when determining that the set tap coefficient cannot be received as a result of the determination in the S3 and a step (S5) for acquiring the tap coefficient so that the training signal before transmission and the output signal are similar by using the tap coefficient matrix W, the output signal matrix Y and the delay matrix U obtained in the step S4 are performed. After the S5, the S3 is performed again. |
