  1. 1. Edge Service Selection in a Virtual Service Marketplace

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wenhao Li; [2020]
    Keywords : Marketplace; service selection; mobile edge; edge-based services; edge infrastructure services.; Marknadsplats; val av tjänster; mobilkant; kantbaserade tjänster; infrastrukturtjänster.;

    Abstract : A brokerless edge service marketplace could play a significant role in enabling an eco- system where a large number of edge providers and Communication Service Providers (CSPs) offer Mobile Edge Infrastructure Services (EISs) to providers of edge-based applications and services. The marketplace would be the bridge between EIS providers and their customers, managing the relations between actors in the mobile edge eco- system. READ MORE

  3. 2. Detection of Emergency Signal in Hearing Aids using Neural Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Abstract : 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. READ MORE

  4. 3. FPGA Implementation of Flexible Interpolators and Decimators

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Dabbugottu VenkataVikram; [2013]
    Keywords : Interpolation; Decimation; Linear-phase FIR interpolation; VHDL implementation of interpolators and decimators;

    Abstract : The aim of this thesis is to implement flexible interpolators and decimators onField Programmable Gate Array (FPGA). Interpolators and decimators of differentwordlengths (WL) are implemented in VHDL. The Farrow structure is usedfor the realization of the polyphase components of the interpolation/decimationfilters.

  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. Simulation of microphone inaccuracies and robustness analysis of Beamformers inside a reverberant environment

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ADITYA SRI TEJA PALANKI; [2012]
    Keywords : Speech Enhancement; Beamformer; Reverberation; Hearing Aids; Noise Cancellation; Fractional Delay; Binaural hearing; Source localization; Echo Cancellation;

    Abstract : All Speech Processing Equipments like noise cancelling headphones and Hearing aids should be able to filter different kinds of interfering signals and present a clear sound to the listener. The effect of these interfering signals varies depending on the surroundings. READ MORE
