    Sammanfattning : The next generations of cellular networks are expected to provide explosive data rate transmissions and very low latencies. To meet such demands, one of the promising wireless transmissions candidates is in-band full-duplex communications, which enable wireless devices to simultaneously transmit and receive on the same frequency channel.

  5. 4. Spectrum Assignment Policy: Towards an Evaluation of Spectrum Commons in Thailand

    Författare :Nattawut Ard-Paru; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; collective use of spectrum; spectrum management; benefit and cost analysis; spectrum assignment; spectrum commons;

    Sammanfattning : There is consensus among economists, engineers, and lawyers that a traditional command-and-control approach to spectrum assignment is inefficient and that a market-based or commons approach can be more efficient. The purpose of this thesis is to find the benefits of using spectrum commons for frequency assignment in Thailand. LÄS MER

  7. 5. Head Movement Correlates to Focus Assignment in Swedish

    Författare :Sonia Sangari; Bertil Lydberg; Lars Ahrenberg; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Speech communication normally involves not only speech but also face and head movements. In the present investigation, the correlation between head movement and focus assignment is studied, both in the laboratory and in spontaneous speech, with the aim of finding out what these head movements look like in detail.
