Abstract
Provided are an apparatus and a method for compensating signal distortion caused by noise. The apparatus comprises a noise reduction unit which reduces noise of an input signal including non-zero mean random noise, and a signal compensator which compensates the output signal of the noise reduction unit so that a signal distortion due to the non-zero mean random noise is removed from the output signal of the noise reduction unit.
