Modeling and analysis of background Noise suppression and cancellation Using intelligent techniques for Speech quality improvement

Abstract

The purpose of communication system is to transmit and receive newlineinformation truly and safely There are two types of communication systems newlinenamely wired and wireless The information through the medium of newlinetransmission is likely to be distorted and corrupted due to noise In order to newlinesuppress and eliminate that kind of noise it is necessary to have several newlinesubsystems such as suppression system and filter system before the signal is newlineprocessed by the receiver The estimation of information signal from the newlinedistorted signal is done using techniques like Generalized Side cvelobe newlineCanceller GSC Adaptive beam forming Log spectral amplitude estimator newlineand Adaptive Noise Cancellation ANC One of the most well known newlinetechniques is ANC newline newline
