Abstract
An apparatus and a method for canceling noise in a voice signal in an electronic apparatus are provided. The apparatus includes a Generalized Sidelobe Canceller (GSC) and a decision unit. The GSC cancels noise components from signals with different phases input via a plurality of microphones. The decision unit estimates a Signal-to-Noise Ratio (SNR) of an input signal to determine a step-size of a filter included in the GSC.
