  1. 21. Building and Evaluating a 3D Scanning System for Measurementsand Estimation of Antennas and Propagation Channels

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Erik Johannes Aagaard Fransson; Tobias Wall-Horgen; [2012]
    Keywords : 3D field scanner; radio propagation channel; virtual array; MIMO; Angle-of-Arrival; regularization; inverse problem; L-curve; truncated singular value decompositions; successive interference cancellation; horn antenna; phase center.;

    Abstract : Wireless communications rely, among other things, on theunderstanding of the properties of the radio propagationchannel, the antennas and their interplay. Adequate measurementsare required to verify theoretical models and togain knowledge of the channel behavior and antenna performance. READ MORE

  3. 22. 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

  4. 23. Performance analysis of Speech enhancement methods in Hands-free Communication with emphasis on Wiener Beamformer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Santhu Renu Vuppala; [2012]
    Keywords : Beamformer; Speech Enhancement; Echo Cancellation.;

    Abstract : The main objective of this thesis, which is a collaborative work between a group of four, is to remove the unwanted components i.e. background noise present in speech signal which affects in the hands-free speech communication. The background noise i. READ MORE

  5. 24. Interference Management for Heterogeneous Networks in 3GPP LTE Advanced and Beyond

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Asif Ali Khan; [2011]
    Keywords : ;

    Abstract : The primary goals of the thesis study were to evaluate the Closed Subscriber Group (CSG) based Heterogeneous Network (HetNet) deployments and identify the impact of CSG LPN cells on various system performance metrics (cell throughput, UE throughput and interference levels etc.) in contrast to the case when Open Access (OA) LPN cells are deployed in the macro cell area.

  6. 25. Acoustic Beamforming for Hearing Aids Using Multi Microphone Array by Designing Graphical User Interface

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : S S V SUMANTH KOTTA; BULLI KOTESWARARAO KOMMINENI; [2011]
    Keywords : Acoustic Beamforming; Array signal processing; Beam steering; Direction of arrival estimation; Distortion measurement; Interference cancellation; Microphone arrays; Noise cancellation; Speech enhancement.;

    Abstract : Hearing impaired persons lose their ability to distinguish speech signal in ambient noise. Human hearing system is sensitive to interfering noise. Interfering noise decreases the quality and intelligibility of the speech signal which in turn makes speech communication default. READ MORE
