Abstract
An adaptive equalizer includes: a speculative equalization circuit which operates a plurality of first tap coefficients with respect to input data and selects operation data corresponding to the input data from a plurality of operation data obtained by the operation; and an adaptive equalization circuit which generates the plurality of first tap coefficients, on the basis of the input data. The adaptive equalization circuit includes: an operation circuit which selects one of a plurality of second tap coefficients corresponding to the plurality of first tap coefficients and operates the selected second tap coefficient with respect to the input data; and a tap coefficient generation circuit which generates the plurality of first tap coefficients, on the basis of operation data obtained by the operation of the operation circuit, when the second tap coefficient selected at the time of the operation in the operation circuit corresponds to the first tap coefficient used for the operation of the operation data selected in the speculative equalization circuit.
