2. 6. On Tailbiting Codes from Convolutional Codes

   Author : Per Ståhl; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer technology; Systems engineering; Teknik; Technological sciences; encoder inverse; systematic feedback encoder; state complexity; trellis; tailbiting termination method; tailbiting code; channel coding; convolutional code; Data- och systemvetenskap; Informatics; systems theory; Informatik; systemteori;

   Abstract : Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. READ MORE

4. 7. Practical Anytime Codes

   Author : Leefke Grosjean; Lars K. Rasmussen; Ragnar Thobaben; Michael Lentmaier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The demand of an increasingly networked world is well reflected in modern industrial control systems where communication between the different components of the system is more and more taking place over a network. With an increasing number of components communicating and with hardware devices of low complexity, the communication resources available per communication link are however very limited. READ MORE

5. 8. Taming of the BEAST

   Author : Maja Loncar; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; tree search; product codes; list distance; list decoding; list-based SISO decoding; ML decoding; MAP decoding; iterative decoding; ISI equalization; BEAST; block codes; Teknik; Signal processing; Signalbehandling;

   Abstract : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. READ MORE

6. 9. Efficient Coding Techniques for Networks & Channels with Transmission Errors

   Author : Ming Xiao; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channels with Errors; Low-Density Generation-Matrix Codes; Sink Bit Error Probability; Continuous Phase Modulation; Maximum-Likelihood Decoding; Cross-Layer Design; Network Coding; Ring Convolutional Codes; Adaptive Codes.; Deterministic Rateless Codes;

   Abstract : This thesis consists of two parts, both of whichinvestigate coding techniques for information transmission throughchannels in the presence of errors. Part I discusses topics ofnetwork coding and rateless codes. Part~II considers channel codesfor continuous phase modulation. These two parts are clearlydifferent, but they are also related.

7. 10. Tales of Tailbiting Codes

   Author : Marc Handlery; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum-likelihood decoding algorithm; minimum distance; active distance; woven convolutional code; tailbiting termination method; convolutional code; tailbiting code; Informatics; systems theory; Informatik; systemteori;

   Abstract : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. READ MORE
