  2. 1. The Information-Theoretic Cost of Learning Fading Channels

    Author : Wei Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; finite blocklength; outage capacity; block-fading channel; Shannon capacity; quasi-static fading;

    Abstract : Recent results in communication theory suggest that significant throughput gains in wireless fading networks can be achieved by exploiting network coordination (e.g., CoMP, network MIMO, and interference alignment), provided that each node in the network has perfect channel knowledge.

  4. 2. Fading Channels: Capacity and Channel Coding Rate in the Finite-Blocklength Regime

    Author : Wei Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Information-theoretic studies on the fundamental limits of communication over wireless fading channels typically rely on simplifying assumptions, such as perfect channel state information (CSI), infinite blocklength, and vanishing probability of error. Although these assumptions are reasonable for most of the current wireless communication systems, they may be inaccurate for next-generation wireless systems. READ MORE

  5. 3. Bounds on the maximum coding rate of multiple-access channels and feedback channels

    Author : Rahul Devassy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : We provide upper and lower bounds on the coding rate of multiple-access channels (MACs) and feedback channels.Traditional MACs have been extensively studied under the assumption of availability of perfect channel state information (CSI).In Paper A we relax this assumption for a Rayleigh block-fading MAC and provide bounds on the sum-rate capacity.

  6. 4. Performance Trade-offs for Ultra-Reliable Low-Latency Communication Systems

    Author : Sebastian Schiessl; James Gross; Mikael Skoglund; Cenk Gursoy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this dissertation, we consider wireless systems for ultra-reliable low-latency communication (URLLC). URLLC systems are required for example in industrial closed loop control systems, where data must be transmitted within a short target delay of at most a few milliseconds. READ MORE

  7. 5. Wireless transmission in future cyber-physical systems

    Author : Hasan Basri Celebi; Mikael Skoglund; Petar Popovski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis studies some fundamental aspects of wireless communication in future cyber-physical systems with special emphasis on constraints on computational complexity and channel state information (CSI) at the transmitter. First, major challenges in designing a suitable wireless communication solution for future cyber-physical systems are initially discussed. READ MORE
