A receiver includes a memory for storing DC offset amounts generated by an analog circuit; an amplifier; a DC offset amount generator for generating a first offset value and a second offset value to be removed from the received signal amplified at the amplifier; a first DC offset component-removing unit for removing the first DC offset value from the received signal before the amplifier; a second DC offset component-removing unit for removing the second DC offset value from the received signal after the amplifier; and an updating unit for updating the DC offset amount stored in the memory in view of the second DC offset value generated by the DC offset amount generator. A maximum value of the second DC offset value is set larger than a multiplication value of a gain of the amplifier by a minimum resolution value of the first DC offset value.
