  1. 1. Detection of Emergency Signal in Hearing Aids using Neural Networks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Vamshi Krishna Lakum; Arshini Gubbala; [2014]
    Nyckelord : Microphone Array; Fractional Delay; Beam Former; Adaptive Algorithms; Neural Networks;

    Sammanfattning : ABSTRACT The detection of an emergency signal can be estimated by the cancellation of surrounding noise and achieving the desired signal in order to alert the automobilist. The aim of the thesis is to detect the emergency signal arriving nearer to the automobilist carrying hearing aids. LÄS MER

  3. 2. Adaptive Signal Processing for SAR Data : Theory and Experimental Results

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Xiao Luo; [2014]
    Nyckelord :Adaptive filtering; LMS Algorithm; NLMS Algorithm; LLMS Algorithm; RLS Algorithm; MATLAB simulation;

    Sammanfattning : This thesis presents the theory and the experiment results with adaptive filtering algorithms. The experiments are based on the ultrawideband (UWB) Synthetic Aperture Radar (SAR) data. LÄS MER

  4. 3. Acoustic Echo cancellation inside a Conference Room using Adaptive Algorithms

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Gannamaneni Geetha Chowdary; [2012]
    Nyckelord :Acoustic echo cancellation; Room modeling; Reverberation time; Signal to noise ratio; Echo return loss enhancement;

    Sammanfattning : The whole dimension of communications has been changed by the rapid growth of technology. Today people are more interested in hands-free com-mucation, which makes use of loud speaker and high gain microphone, in place of the old modeled wired telephone. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Swathi Kotte; [2011]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
