[Wiener-Filtering-for-Speech-Enhancem...] - Normally speech signals are contaminated with noise and interference that reduces the intelligibility of speech during communication. In order to make speechsignals e ective and useful, they need to be enhanced from the noisy speech signal.In speech processing eld many speech enhancement techniques are developed andare providing very good results.Multichannel microphone array is also one of the techniques used for speechenhancement, that provides better results than the single channel speech enhancement. Moreover, Wiener ltering is the most commonly used technique formultichannel microphone array for speech enhancement. The main focus of thisthesis is to implement multichannel microphone array using Wiener ltering inthe modulation domain system and also in the time domain system to enhancethe speech.
