Adaptive equalizer

Abstract

An adaptive equalizer capable of suppressing an increase in circuit scale and an increase in operation clock frequency. An adaptive equalizer (100) performs an adaptive equalization process on a time-region signal in a frequency region. A signal converter (200) has: a first wide-bit memory (201) capable of reading/writing a plurality of sample signals; a first register group (202) comprising a plurality of registers capable of accessing the first wide-bit memory (201); a butterfly computation unit group (204) comprising a plurality of butterfly computation units; and a first connection switching unit (203) for switching the state of connection between the plurality of registers and the plurality of butterfly computation units.
