  2. 1. Analysis of Relay Channels and Improved Iterative Decoders for Turbo-Coded Decode-and-Forward Relay Channels

    Author : Khoa Huynh; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; detect-and-forward; maximum a posteriori; decode-and-forward; Maximum likelihood; iterative decoder.; relay channels; equivalent SNR; upper bound;

    Abstract : Three-node relay channels which consist of a source, a relay and a destinationare considered in this thesis. In the first part, an uncoded relay channelis studied. READ MORE

  4. 2. Relaying Protocols for Wireless Networks

    Author : Majid Nasiri Khormuji; Erik G. Larsson; Christian Ibars; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; The relay channel; constellation rearrangement; decode-and-forward; resource allocation; Telecommunication theory; Telekommunikationsteori;

    Abstract : Motivated by current applications in multihop transmission and ad hoc networks, the classical three-node relay channel consisting of a source-destination pair and a relay has received significant attention. One of the crucial aspects of the relay channel is the design of proper relaying protocols, i.e. READ MORE

  5. 3. Coding Schemes for Relay Networks

    Author : Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Relay networks; capacity; decode-and-forward; amplify-andforward; compress-and-forward; nonlinear relaying; noisy network coding; hybrid relaying; Telecommunication; Telekommunikation;

    Abstract : Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attention.

  6. 4. Coding and Transmission Strategies for Secrecy

    Author : Mattias Andersson; Mikael Skoglund; Matthieu Bloch; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model.

  7. 5. Cooperative Strategies in Multi-Terminal Wireless Relay Networks

    Author : Jinfeng Du; Mikael Skoglund; Ming Xiao; Lizhong Zheng; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative communication; relay; network coding; network information theory; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Smart phones and tablet computers have greatly boosted the demand for services via wireless access points, keeping constant pressure on the network providers to deliver vast amounts of data over the wireless infrastructure. To enlarge coverage and enhance throughput, relaying has been adopted in the new generation of wireless communication systems, such as in the Long-Term Evolution Advanced standard,  and will continue to play an important role in the next generation wireless infrastructure.
