   Sammanfattning : Error control coding is an essential part of any well-designed digital communication system. It has been used in structures to protect the information, by enabling reliable delivery of digital data over unreliable communication channels. Even though this is an old topic, enlisted by Shannon in the late 40's, a lot of research is still going on. LÄS MER

3. 2. On the M*-BCJR and LISS Algorithms for Soft-Output Decoding of Convolutional Codes

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Jacob Larsson; Fredrik Wesslén; [2006]
   Nyckelord :Technology and Engineering;

   Sammanfattning : To communicate reliably over noisy wireline or wireless channels, algorithms that add redundancy are used to help reconstruct the transmitted sequence at the receivers. Such error control coding algorithms are today used in all digital communication systems. LÄS MER
