2. 1. Source-Channel Coding in Networks

   Author : Niklas Wernersson; Mikael Skoglund; Geoffrey Chan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source coding; channel coding; joint source-channel coding; bandwidth expansion; distributed source coding; multiple description coding; soft decoding; Telecommunication; Telekommunikation;

   Abstract : The aim of source coding is to represent information as accurately as possible using as few bits as possible and in order to do so redundancy from the source needs to be removed. The aim of channel coding is in some sense the contrary, namely to introduce redundancy that can be exploited to protect the information when being transmitted over a nonideal channel. READ MORE

5. 3. Complex source modeling for electromagnetic dosimetry

   Author : Markus Johansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; phase-retrieval; source modeling; dosimetry; SAR;

   Abstract : Electromagnetic modeling of complex sources is useful in dosimetry applications as well as for near-field to far-field transformations and antennadiagnostics. In order to determine whether exposure safety guidelines, such as the EU directive 2004/40/EC, are complied with, it is important to be able tomodel the field distribution from electromagnetic sources.

6. 4. Phase Retrieval Methods for Electromagnetic Source Modeling

   Author : Markus Johansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source modeling; optimization; SAR; phase retrieval; dosimetry;

   Abstract : Modeling of the field distributions from electromagnetic sources is of interest for various applications including electromagnetic compatibility investigations, near-field to far-field transformations, antenna diagnostics and electromagnetic dosimetry. In order to determine whether exposure safety guidelines, such as the EU directive 2004/40/EC, are complied with, source modeling methods are important. READ MORE
