  1. 1. Robust Echo-Cancellation for Simple VoIP-Applications in Embedded Systems

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Anton Eriksson; [2015]
    Keywords : VoIP; Adaptive Filtering; Signal Processing;

    Abstract : Voice over IP (VoIP) is the group of techniques for delivering voice communications over Internet Protocol (IP) networks. It has mainly served as the possible substitution for regular PSTN over the last decades, but has recently gained an increased interest in various areas such as alarm applications and customer service.

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

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Abstract : 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. READ MORE

  4. 3. Adaptive filters applied on radar signals

    University essay from Signaler och System

    Author : Daniel Salminen; [2013]
    Keywords : LMS; RLS; adaptive filters; radar;

    Abstract : This master thesis has been performed at SAAB AB in Järfälla, Sweden.A radar warning receiver must alert the user when someone highlights it with radarsignals. Radar signals used today varies and has a wide frequency band. In order todetect all possible radar signals the radar warning receiver must have a widebandwidth. READ MORE

  5. 4. Adaptive Sub band GSC Beam forming using Linear Microphone-Array for Noise Reduction/Speech Enhancement.

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mamun Ahmed; [2012]
    Keywords : Generalized Side lobe Canceller GSC ; Blocking matrix; Microphone array; Sub band; SNR. ;

    Abstract : This project presents the description, design and the implementation of a 4-channel microphone array that is an adaptive sub-band generalized side lobe canceller (GSC) beam former uses for video conferencing, hands-free telephony etc, in a noisy environment for speech enhancement as well as noise suppression. The side lobe canceller evaluated with both Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) adaptation. READ MORE

  6. 5. Adaptive Speech enhancement system using Linear Microphone-array for noise Reduction

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Jeevan Reddy Yarragudi; [2012]
    Keywords : Speech enhancement; Beam former; Generalized side lobe canceler; LMS algorithm ;

    Abstract : A major part of the interaction between humans takes place via speech communication. It is very difficult to understand speech signals in presence of background noise for the normal listeners and hearing impaired persons. The human speech and hearing organ is inherently sensitive to interfering noise. READ MORE
