3. 2. Adaptive Sub band GSC Beam forming using Linear Microphone-Array for Noise Reduction/Speech Enhancement.

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Mamun Ahmed; [2012]
   Keywords : Generalized Side lobe Canceller GSC ; Blocking matrix; Microphone array; Sub band; SNR. ;

   Abstract : This project presents the description, design and the implementation of a 4-channel microphone array that is an adaptive sub-band generalized side lobe canceller (GSC) beam former uses for video conferencing, hands-free telephony etc, in a noisy environment for speech enhancement as well as noise suppression. The side lobe canceller evaluated with both Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) adaptation. READ MORE

4. 3. Adaptive Speech enhancement system using Linear Microphone-array for noise Reduction

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Jeevan Reddy Yarragudi; [2012]
   Keywords : Speech enhancement; Beam former; Generalized side lobe canceler; LMS algorithm ;

   Abstract : A major part of the interaction between humans takes place via speech communication. It is very difficult to understand speech signals in presence of background noise for the normal listeners and hearing impaired persons. The human speech and hearing organ is inherently sensitive to interfering noise. READ MORE

   Abstract : Now a day’s communication through laptops is drastically increasing in numerous fields. During the communication between person to person through laptops the speech signals is contaminated by the other speech interference signals. READ MORE

6. 5. Acoustic Beamforming for Hearing Aids Using Multi Microphone Array by Designing Graphical User Interface

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : S S V SUMANTH KOTTA; BULLI KOTESWARARAO KOMMINENI; [2011]
   Keywords : Acoustic Beamforming; Array signal processing; Beam steering; Direction of arrival estimation; Distortion measurement; Interference cancellation; Microphone arrays; Noise cancellation; Speech enhancement.;

   Abstract : Hearing impaired persons lose their ability to distinguish speech signal in ambient noise. Human hearing system is sensitive to interfering noise. Interfering noise decreases the quality and intelligibility of the speech signal which in turn makes speech communication default. READ MORE
