Abstract
A receiver includes a memory for storing DC offset amounts in accordance with a DC offset component remaining in a received signal; a first DC offset component-removing unit configured so as to generate a first DC offset amount from the DC offset amounts stored in the memory and to remove the first DC offset amount from the received signal; an amplifier for amplifying a signal output from the first DC offset component-removing unit; and a second DC offset component-removing unit configured so as to generate a second DC offset amount from the DC offset amounts stored in the memory in view of a gain of the amplifier and remove the second DC offset amount from the signal amplified by the amplifier.
