1. 1. Coordinated Transmission for Wireless Interference Networks

   Författare :Hamed Farhadi; Mikael Skoglund; David Gesbert; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference; Wireless Network; MIMO; Coordinated Transmission; Resource Allocation; Interference Alignment; Scheduling; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless interference networks refer to communication systems in which multiple source–destination pairs share the same transmission medium, and each source’s transmission interferes with the reception at non-intended destinations. Optimizing the transmission of each source–destination pair is interrelated with that of the other pairs, and characterizing the performance limits of these networks is a challenging task. LÄS MER

3. 2. Base Station Coordination in Multicell MIMO Networks

   Författare :Nima Seifi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; Antenna tilt; intercell interference; base station coordination; scheduling.;

   Sammanfattning : The use of multi-antenna technology, also referred to as multiple-input multipleoutput (MIMO), has been shown to improve both the achievable data rates and the link reliability in single-cell wireless systems without a need for extra power or bandwidth. The promised gains of MIMO techniques are, however, severely degraded in a multicell environment due to the presence of intercell interference,especially for users at the cell edge. LÄS MER

4. 3. Coordinating the Internet

   Författare :Fredrik Lindeberg; Alf Westelius; Nils-Göran Olve; Bertil Thorngren; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; internet; internet coordination; internet governance; coordination; Economic Information Systems; Ekonomiska informationssystem;

   Sammanfattning : Många självklarheter i vårt digitala samhälle är beroende av Internet för att fungera. Allt från smarta dörrar för hemtjänster, till självscanningsapparaterna på ICA, till nyare bilar, moderna tillverkningsrobotar, telefoner och affärssystem. LÄS MER

5. 4. Distributed Coordination in Multiantenna Cellular Networks

   Författare :Rasmus Brandt; Mats Bengtsson; Joakim Jaldén; Ignacio Santamaría; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multicell MIMO; base station clustering; coordinated precoding; branch and bound; coalitional game theory; intercluster interference; CSI acquisition; hardware impairments; discrete rate selection; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless communications are important in our highly connected world. The amount of data being transferred in cellular networks is steadily growing, and consequently more capacity is needed. This thesis considers the problem of downlink capacity improvement from the perspective of multicell coordination. LÄS MER
