  1. 1. Convergence Analysis and Design of Multiple Concatenated Codes

    Author : Fredrik Brännström; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extrinsic information transfer EXIT function; convergence analysis; Multiple concatenated codes; code search; scheduling; parameter estimation; iterative decoding; EXIT chart; puncturing;

    Abstract : The objective of this thesis is to develop a methodology for designing efficient multiple concatenated coding schemes, consisting of two or more constituent codes, concatenated in serial or in parallel. Extrinsic information transfer (EXIT) analysis is found to be a suitable and versatile analysis tool for such codes and thus, the design methodology is based almost entirely on this technique.

  2. 2. Adaptive Concatenated Coding for Wireless Real-Time Communications

    Author : Elisabeth Uhlemann; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Incremental redundancy hybrid ARQ; Multiple concatenated codes; Iterative decoding; Rate compatible punctured codes; Union bounds; EXIT charts; Convergence analysis; Wireless real-time communication; Quality of service; TECHNOLOGY; TEKNIKVETENSKAP; convergence analysis; quality of service; rate compatible punctured codes; multiple concatenated codes; iterative decoding; wireless real-time communication; incremental redundancy hybrid ARQ; union bounds;

    Abstract : The objective of this thesis is to improve the performance of real-time communication overa wireless channel, by means of specifically tailored channel coding. The deadlinedependent coding (DDC) communication protocol presented here lets the timeliness and thereliability of the delivered information constitute quality of service (QoS) parametersrequested by the application.
