  1. 1. 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

  3. 2. Disturbing Sound Cancellation Using System Identification

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Keywords : System Identification; MATLAB; Disturbing Sound Cancellation; NMSE; Model;

    Abstract : Disturbing sound sometimes should be cancelled when music has been recorded. In this thesis, MATLAB was used as a tool. System identification was a main method used to find the unknown system. By subtracting the simulated output, disturbing sound was cancelled. READ MORE

  4. 3. Disturbing Sound Cancellation

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Deyue Yu; [2010]
    Keywords : System Identification Matlab Digital Signal Processing Linear ARX Model;

    Abstract : When doing recording work in the studio, disturbing sound must be removed. In this thesis, the purpose of this thesis is to formulate a mathematical equation, by using MATLAB to identify a system, then using the system to do cancellation of disturbing sound. READ MORE
