4. 18. Transceiver Design for Multiple Antenna Communication Systems with Imperfect Channel State Information

   Författare :Xi Zhang; Björn Ottersten; Miguel Lagunas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; imperfect CSI; linear transceiver; beamforming; user selection; robust design; channel statistics; Telecommunication; Telekommunikation;

   Sammanfattning : Wireless communication links with multiple antennas at both the transmitter and the receiver sides, so-called multiple-input-multiple-output (MIMO)systems, are attracting much interest since they can significantly increase the capacity of band-limited wireless channels to meet the requirements of the future high data rate wireless communications. The treatment of channel state information (CSI) is critical in the design of MIMO systems. LÄS MER

5. 19. Increasing the Value of Data in Production Systems

   Författare :Maja Bärring; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industry 4.0; digitalization; data; Digital technologies; decision support; manufacturing; Smart Manufacturing;

   Sammanfattning : A digital transformation is taking place, where information is available about almost anything, changing how work is performed and anticipated. More digitized information enabled by the digital technologies is supporting businesses to measure more about their processes and thereby also to know more. LÄS MER

7. 20. A flexible framework for detection of feature interactions in telecommunication systems

   Författare :Gustaf Naeser; Bengt Jonsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Systems; Datorteknik;

   Sammanfattning : The complexity of today's telecommunications systems grows with each new feature introduced. As the number of services an operator provides can be used to gain advantage over competitors the number of services will continue to increase. LÄS MER
