  2. 11. Characterization and Enhancement of Antenna System Performance in Compact MIMO Terminals

    Author : Vanja Plicanic; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Co-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multiple-output (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal multiple-antenna systems in user terminals.

  4. 12. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis

    Author : Jens Forsberg; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; proteolysis; Plant biochemistry; protease; two-component systems; protein kinase; protein phosphorylation; state transitions; light-harvesting antenna; photosynthesis; chloroplast;

    Abstract : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. READ MORE

  5. 13. Characterization of Terminal Antennas for Diversity and MIMO Systems by Theory, Simulations and Measurements in Reverberation Chamber

    Author : Kent Rosengren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mode stirred chamber; embedded pattern; channel capacity; radiation efficiency; reverberation chamber; embedded element; MIMO; diversity gain;

    Abstract : This thesis is based on the work of designing and building a small reverberation chamber, and to use this chamber for characterization of antennas on mobile terminals such as phones. The characterization is done in terms of radiation efficiency, diversity gain and maximum available capacity. READ MORE

  6. 14. EMF Exposure and Radiation Performance of Millimeter-Wave Antennas in 5G Mobile Terminals

    Author : Bo Xu; Sailing He; Oscar Quevedo-Teruel; Akimasa Hirata; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Since 2019, 5G has been rolled out in many countries. To support the demand of increasing traffic capacity, for the first time, the millimeter-wave (mmWave) frequency spectrum is exploited for the mobile wireless telecommunication technologies. READ MORE

  7. 15. A Statistical-Physics Approach to the Analysisof Wireless Communication Systems

    Author : Maksym Girnyk; Lars K. Rasmussen; Giuseppe Caire; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless communications; statistical physics; random matrix theory; large-system analysis; MIMO; 5G; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Multiple antennas at each side of the communication channel seem to be vital for future wireless communication systems. Multi-antenna communication provides throughput gains roughly proportional to the smallest number of antennas at the communicating terminals. READ MORE
