  2. 6. Coding of Three-dimensional Video Content : Diffusion-based Coding of Depth Images and Displacement Intra-Coding of Plenoptic Contents

    Author : Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Touradj Ebrahimi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent years, the three-dimensional (3D) movie industry has reaped massive commercial success in the theaters. With the advancement of display technologies, more experienced capturing and generation of 3D contents, TV broadcasting, movies, and games in 3D have entered home entertainment, and it is likely that 3D applications will play an important role in many aspects of people's life in a not distant future.

  4. 7. Source-channel coding for closed-loop control

    Author : Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

    Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE

  5. 8. On Robust LPC-spectrum Coding and Vector Quantization

    Author : Roar Hagen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robustness against channel noise; LPC-spectrum coding; vector quantization; speech coding; linear mapping of a block code;

    Abstract : Digital speech coding is concerned with representing a discrete-time speech signal with as few bits per second as possible without introducing annoying artifacts in the coded speech. Many modern speech coders are based on Linear Predictive Coding (LPC) which employ a source-filter model for speech production. READ MORE

  6. 9. Analysis of Some Convolutional Coding Constructions

    Author : Karin Engdahl; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-codes; low-density parity-check convolutional codes; low-density codes; PSK; PAM; QAM; coded modulation; multilevel coding; convolutional codes; multilevel modulation; iterative decoding; Informatics; systems theory; Informatik; systemteori;

    Abstract : This thesis focuses on different convolutional coding constructions for digital communication systems, and on methods to analyze these constructions. The work presented in the thesis can be divided into three main areas; error probability bounds for convolutional codes, analysis of multilevel modulation, and investigation of low-density parity-check convolutional codes.
