Abstract

This paper provides the noise reduction for dual microphone in mobile phone. The method for noise reduction is based upon the filtering technology. In this paper compare the desired signal with the IIR, FIR, Adaptive filter output and improve the performance of mobile phone by reduction of noise in mobile phones. Noise suppression has application in virtually all field of communication (channel equalization, radar signal processing etc).
