  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

  2. 2. Implementation of the LMS Algorithm for Noise Cancellation on Speech Using the ARM LPC2378 Processor.

    University essay from Växjö universitet/Matematiska och systemtekniska institutionen; Växjö universitet/Matematiska och systemtekniska institutionen

    Author : Cesar Augusto Azurdia Meza; Yaqub Jon Mohamadi; [2009]
    Keywords : Signal Processing; Digital Filters; LMS Algorithm; Noise Cancellation; Digital Processors;

    Abstract : On this thesis project, the LMS algorithm has been applied for speech noise filteringand different behaviors were tested under different circumstances by using Matlabsimulations and the LPC2378 ARM Processor, which does the task of filtering in realtime. The thesis project is divided into two parts: the theoretical and practical part. READ MORE
