2. 1. Coordinated Transmission for Wireless Interference Networks

   Author : Hamed Farhadi; Mikael Skoglund; David Gesbert; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Coordinated MultiPoint Transmission with Incomplete Information

   Author : Tilak Rajesh Lakshmana; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; precoding; coordinated multipoint; joint transmission; backhauling; particle swarm optimization; decentralized; stochastic optimization; convex optimization; efficient backhauling; centralized;

   Abstract : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. READ MORE

5. 3. Cross-layer Aspects in OFMDA Systems : Feedback, Scheduling and Beamforming

   Author : Patrick Svedman; Björn Ottersten; Ana I. Pérez-Neira; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : This thesis mainly studies the downlink of a wireless multiuser system, where the transmitter has limited knowledge about the communication channels of the users. Key techniques to improve the performance of such systems are, for instance, multiple antennas, multiuser diversity and orthogonal frequency-division multiple access (OFDMA). READ MORE

6. 4. Share-Driven Scheduling of Embedded Networks

   Author : Thomas Nolte; Hans Hansson; Christer Norström; Sasikumar Punnekkat; Luís Almeida; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; subsystem integration; controller area network; CAN; real-time communication; real-time analysis; server-based scheduling; Server-CAN; Computer engineering; Datorteknik; Datavetenskap;

   Abstract : Many products are built from more or less independently developed subsystems. For instance, a car consists of subsystems for transmission, braking, suspension, etc. These subsystems are frequently controlled by an embedded computer system. READ MORE

7. 5. Latency Reduction for Soft Real-Time Traffic using SCTP Multihoming

   Author : Johan Eklund; Anna Brunström; Thomas Dreibholz; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transport protocol; SCTP; multihoming; latency; performance evaluation; failover; concurrent multipath transfer; scheduling; mobility; handover; Computer Science; Datavetenskap;

   Abstract : More and more so-called soft real-time traffic is being sent over IP-based networks. The bursty, data-limited traffic pattern as well as the latency requirements from this traffic present challenges to the traditional communication techniques, designed for bulk traffic without considering latency.
