  1. 6. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
    Keywords : Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

    Abstract : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. READ MORE

  2. 7. Geotermisk fjärrvärme i Gunsta

    University essay from SLU/Dept. of Energy and Technology

    Author : Caroline Krouthén; Andreas Lundgren; Per Mandfloen; Karl-Oskar Sandberg; Johanna Sjöberg-Högerås; Johan Thorell; Svante Wärnsberg Monie; [2014]
    Keywords : geotermi; geotermisk energi; fjärrvärme; Gunsta; förnybar; värmekälla; värmeproduktion;

    Abstract : Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16. READ MORE

  3. 8. Understanding and Development of Inter-cell Interference Mitigation mechanism in LTE-A Heterogeneous Network

    University essay from Avdelningen för fysik och elektroteknik

    Author : Bilal Shah; Suman Ghimire; [2013]
    Keywords : ;

    Abstract : In long term evolution Advanced (LTE-A), concept of heterogeneous network (HetNet) has been introduced. Since, spectrum has become a rare resource these days; another mean is to be looked after to improve the existing wireless technology. One possible way is to improve the network topology so that frequency spectrum can be reused. READ MORE

  4. 9. Stereo coding for the ITU-T G.719 codec

    University essay from Signaler och System

    Author : Tomas Jansson; [2011]
    Keywords : stereo coding; ITU-T G.719; audio; stereo models; stereokodning; ITU-T G.719; ljud; stereomodeller;

    Abstract : This thesis presents a stereo coding architecture for the ITU-T G.719 fullband mono codec. G.719 is suitable for teleconferencing applications with a competitive audio quality for speech and audio signals that are encoded at 32, 48 and 64 kbps. READ MORE

  5. 10. Heat storage in lead-acid accumulators on-board submarines.

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hed Henrik; [2011]
    Keywords : heat storage lead-acid accumulators submarines; Technology and Engineering;

    Abstract : A Swedish submarine often operates in colder waters, resulting in a cold on-board climate and a low temperature in the batteries. The batteries reaches their maximum capacity when they are at a temperature of 30°C, which they rarely are during the winter months when the temperature often is lower than 7°C. READ MORE
