6. On Spectrum Sensing for Secondary Operation in Licensed Spectrum : Blind Sensing, Sensing Optimization and Traffic Modeling
Sammanfattning : There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. LÄS MER
7. Blinda personers icke-verbala kommunikation : studier om kroppsspråk, icke-verbal samtalsreglering och icke-verbala uttryck
Sammanfattning : The purpose of this thesis is to deepen the understanding of grown-up blind people’s non-verbal communication, including body expressions and paralinguistic (voice) expressions.

9. Servicescapes seen by visually impaired travellers : Time-geography approach to servicescape research
Sammanfattning : Knowledge gaps remain in the study of servicescapes, since existing research on servicescapes tends to ignore major advances in the understanding of space and time as social phenomena. One aspect that particularly requires further study is how emerging constraints influence customers’ interactions with organized service places. LÄS MER
10. Blind Massive MIMO Base Stations : Downlink Transmission and Jamming
Sammanfattning : Massive MIMO (Multiple-Input--Multiple-Output) is a cellular-network technology in which the base station is equipped with a large number of antennas and aims to serve several different users simultaneously, on the same frequency resource through spatial multiplexing. This is made possible by employing efficient beamforming, based on channel estimates acquired from uplink reference signals, where the base station can transmit the signals in such a way that they add up constructively at the users and destructively elsewhere.
