Abstract
An n-tap (n≧2 (in the case of FIG., n=2)) DFE equalizes a received signal on the basis of a determination result of a signal which has been received, and outputs a determination result of the received signal after equalization. An adjustment section generates a plurality of filter patterns for observation of an inter-symbol interference amount by changing values of n bits included in the plurality of filter patterns. The adjustment section then compares each of the plurality of filter patterns generated with an output data string corresponding to the determination result of the received signal after equalization and adjusts tap coefficients set for n (in the case of FIG.) taps included in the DFE on the basis of adjustment values corresponding to values of the n bits included in a filter pattern which matches the output data string.
