  1. 21. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links

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

    Author : Miguel Olmedo Iglesias; [2012]
    Keywords : ;

    Abstract : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. READ MORE

  2. 22. An Array of First Order Differential Microphone Strategies for Enhancement of Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Naresh Reddy NagiReddy; Arun Kumar Korva; [2012]
    Keywords : speech enhancement; beamforming; microphone array; elko algorithm; wiener beamformer; differential microphone ;

    Abstract : The quality and intelligibility of speech is degraded with the presence of background noise in the speech signal, which affects the listeners ability to understand the speech clearly. Speech enhancement is the process with which the background noise can be suppressed to improve the quality and intelligibility of the speech signal. READ MORE

  3. 23. Self-optimization of Antenna Tilt in Mobile Networks

    University essay from KTH/KTH/Kommunikationssystem, CoSKTH Center för Trådlösa System, Wireless@kth

    Author : Vlad-Ioan Bratu; [2012]
    Keywords : ;

    Abstract : The increased complexity of mobile networks, the need to deliver high data rate services and the variation of mobile traffic put a high burden on operation and maintenance in terms of extra workload and additional costs . New approaches to network optimization and management should be taken into account to increase network performance and reduce operational costs. READ MORE

  4. 24. Performance evaluation of security mechanisms in Cloud Networks

    University essay from KTH/Kommunikationssystem, CoS

    Author : Anand Kannan; [2012]
    Keywords : Cloud Networks; Key management; mobile agent; telco cloud; open flow; Intrusion Detection System IDS ; Genetic Algorithm GA ; Fuzzy Support Vector Machine FSVM ; tenfold cross validation;

    Abstract : Infrastructure as a Service (IaaS) is a cloud service provisioning model which largely focuses on data centre provisioning of computing and storage facilities. The networking aspects of IaaS beyond the data centre are a limiting factor preventing communication services that are sensitive to network characteristics from adopting this approach. READ MORE

  5. 25. Enhancement of Speech Intelligibility using Beamforming Techniques

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : LEELA KRISHNA GUDUPUDI; [2012]
    Keywords : Beamforming; Speech Enhancement; Microphone Arrays; PESQ; Delay-and-Sum;

    Abstract : Speech enhancement is a process of enhancing the intelligibility or quality of speech using various audio processing algorithms. The concept of speech enhancement is the most important field for many applications such as teleconferencing systems, speech recognition, VoIP, mobile phones, hearing aids, etc. [1]. READ MORE
