1. A method for removing a noise signal from an input signal, the method comprising:
- detecting an amount of energy of the input signal;
removing the noise signal from the input signal, the input signal with the noise signal removed being an intermediate output signal; and
amplifying the intermediate output signal, based on a difference between an amount of energy of the intermediate output signal and the amount of energy of the input signal, as a final output signal.

Abstract
A method for removing a noise signal from an input signal that is received. In the method, the amount of energy of the input signal is detected, a noise signal included in the input signal is estimated, an intermediate output signal is generated by removing the estimated noise signal from the input signal, and a final output signal is generated by amplifying the amount of energy of the intermediate output signal based on a difference between the amount of energy of the intermediate output signal and the amount of energy of the input signal.
