6. Performance analysis of different adapative algorithms based on acoustic echo cancellation
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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

7. Microphone Array Wiener Beamforming with emphasis on Reverberation
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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.

8. BLIND DECONVOLUTION AND ADAPTIVE ALGORITHMS FOR DE-REVERBERATION
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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

9. 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 ingenjörsvetenskapAbstract : 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
