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

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

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

    Abstract : 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. READ MORE

  5. 9. Development of Star Tracker Attitude and Position Determination System for Spacecraft Maneuvering and Docking Facility

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Serkan Dikmen; [2016]
    Keywords : star sensor; optical sensor; image processing; vision system; OpenCV; star tracker algorithms; voting methods; star catalog; attitude and position determination; star image; ground station; TCP communication; spacecraft maneuvering and docking facility;

    Abstract : Attitude and position determination systems in satellites are absolutely necessary to keep the desired trajectory. A very accurate, reliable and most used sensor for attitude determination is the star tracker, which orient itself in space by observing and comparing star constellations with known star patterns.
