2. 6. Resource Allocation in Downlink Coordinated Multi-Point Systems

   Author : Jingya Li; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backhaul latency; Coordinated multi-point CoMP transmission; imperfect synchronization; fractional frequency reuse; resource allocation; general duality theory; imperfect channel state information; inter-cluster interference coordination;

   Abstract : The raised user expectations of quality of service and the rapid growth of the data traffics impose a great challenge for mobile communication systems. The performance, e.g., the spectrum efficiency, peak data rate, cell-edge data rate, of current cellular systems ismainly limited due to the presence of inter-cell interference. READ MORE

4. 7. Essays on Asymmetric Information and Environmental Regulation through Disclosure

   Author : Jorge H. García; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social Norm; Imperfect Information; Environmental Policy; Pollution Control; Public Disclosure; Environmental Management; Bayesian Equilibrium; Panel Data; Bivariate Analysis; Indonesia; Central and Eastern Europe.;

   Abstract : This dissertation delves into different aspects of a relatively new policy approach for industrial pollution control: the public dissemination of information by regulators regarding the environmental performance of firms. These schemes are sometimes referred to as regulation through disclosure or informational regulation. READ MORE

5. 8. Simulation-based Optimization and Decision Making with Imperfect Information

   Author : Farzad Kamrani; Rassul Ayani; Stephen John Turner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

   Abstract : The purpose of this work is to provide simulation-based support for making optimal (or near-optimal) decisions in situations where decision makers are faced with imperfect information. We develop several novel techniques and algorithms for simulation-based optimization and decision support and apply them to two categories of problems: (i) Unmanned Aerial Vehicle (UAV) path planning in search operations, and; (ii) optimization of business process models.

6. 9. Ultra-Reliable Short-Packet Communications: Fundamental Limits and Enabling Technologies

   Author : Johan Östman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra-reliable low-latency; variablelength stop-feedback; imperfect CSI; channel estimation; HARQ.; joint detection and decoding; short packets; Block-fading channels; multiuser massive MIMO;

   Abstract : The paradigm shift from 4G to 5G communications, anticipated to enable ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of wireless communication systems. Unlike in 4G systems, where the main objective is to provide a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.

7. 10. Coding for multiple-access and fading channels

   Author : Leif Wilhelmsson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Gilbert-Elliott channel model; Imperfect interleaving; Fading; Error correcting codes; Pre-coding; Channel capacity; Direct-sequence code-division multiple-access DS-CDMA ; Frequency-hopped code-division multiple-access FH-CDMA ; computer technology; Data- och systemvetenskap; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : This thesis treats some information-theoretical and coding aspects of communication over multiple-access and fading channels. It consists of a general introduction and seven papers. In code-division multiple-access (CDMA) communication, many users have access to the channel simultaneously. READ MORE
