  2. 2. Performance analysis of different adapative algorithms based on acoustic echo cancellation

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Nagaswaroopa Adapa; Sravya Bollu; [2013]
    Keywords : Echo Cancellation; Adaptive algorithms; Noise Cancellation; Reverberation; Room Impulse Response; Adaptive filters;

    Abstract : In modern telecommunication systems like hands-free and teleconferencing systems, the problem arise during conversation is the creation of an acoustic echo. This problem degrades the quality of the information signal. READ MORE

  3. 3. Microphone Array Wiener Beamforming with emphasis on Reverberation

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Vamsynagh Pedamallu; [2012]
    Keywords : reverberation; wiener; beamforming; PESQ; SRP-PHAT;

    Abstract : Effective speech communication using microphone array is getting significant research in speech acquisition methods such as speaker localization, noise reduction and tracking. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with noise reduction capability as well as efficiency in speaker localization.

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Keywords : Adaptive algorithms; CMA; Reverberation; Reverberation index; Speech Distortion.;

    Abstract : De-reverberation of speech signals in a hands-free scenario by adaptive algorithms has been a research topic for several years now. However, it is still a challenging problem because of the nature of common room impulse response (RIR). READ MORE

  5. 5. Performance Analysis of Adaptive Algorithms based on different parameters Implemented for Acoustic Echo Cancellation in Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Swathi Kotte; [2011]
    Keywords : least mean square LMS Algorithm; Leaky Least mean square LLMS Algorithm; Normalized Least Mean Square NLMS Algorithm and Recursive Least Square RLS Algorithm ; additive white Gaussian noise ; Return Loss Enhancement ERLE ; signal to noise ratio;

    Abstract : Echo cancellation in voice communication is a process of removing the echo to improve the clarity, quality of the voice signals by suppressing the silence signal which prevents echoes during transmission through networks. There are two types of echo in voice communication: Hybrid echo cancellation and Acoustic echo cancellation. READ MORE
