  1. 21. Household’s energy consumption and productionforecasting: A Multi-step ahead forecast strategiescomparison.

    Master-uppsats, Högskolan Dalarna/Mikrodataanalys

    Författare :Gonzalo Martín-Roldán Villanueva; [2017]
    Nyckelord :Multi-step; forecast; strategies; Recursive; Direct; DirRec; DIRMO; MIMO; Artificial Neural Networks; Random Forest; K-Nearest Neighbours Regression; MAPE; MAE;

    Sammanfattning : In a changing global energy market where the decarbonization of the economy and the demand growth are pushing to look for new models away from the existing centralized non-renewable based grid. To do so, households have to take a ‘prosumer’ role; to help them take optimal actions is needed a multi-step ahead forecast of their expected energy production and consumption. LÄS MER

    Sammanfattning : The wireless smartphone success, applications and services that keep increasing nowadays, raise the demand to provide high bitrate; there is a need to find solutions for that requirement. 5G is the next generation networks that will provide data rates beyond 1Gbps. LÄS MER

  4. 23. Ray-tracing based analysis of channel characteristics and capacity improvement capabilities of spatial multiplexing and beamforming at 15 and 28 GHz

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Qingbi Liao; [2016]
    Nyckelord :5G; 15 GHz; 28 GHz; beamforming; capacity; channel multiplexing richness; hybrid beamforming; MIMO; mm-Wave; ray-tracing; spatial multiplexing; Technology and Engineering;

    Sammanfattning : In the previous decades, mm-Wave frequency bands have largely been ignored for cellular communication because of the high free space attenuation as well as the cost and complexity of mm-Wave RF circuits. However, with the improvement of RF and antenna technologies over the last decade, it has become feasible to con- sider mm-Wave bands for cellular communications. LÄS MER

  5. 24. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Advaita Advaita; Mani Meghala Gali; [2016]
    Nyckelord :Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

    Sammanfattning : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.
