2. 1. Coding and Modulation for Wideband CDMA

   Author : Ola Wintzell; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo codes.; Electronics and Electrical technology; channel coding; impulse radio; coordinated transmission; pre-coding; cellular radio capacity; Direct sequence code division multiple access DS-CDMA ; pulse position hopped code division multiple access PPH-CDMA ; Elektronik och elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells.

4. 2. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

   Author : Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

   Abstract : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. READ MORE

5. 3. Motion estimation for perceptual image sequence coding

   Author : Kenneth Andersson; Håkon Husøy; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes new methods for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/or higher visual quality. READ MORE

6. 4. Coding for multiple-access and fading channels

   Author : Leif Wilhelmsson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Gilbert-Elliott channel model; Imperfect interleaving; Fading; Error correcting codes; Pre-coding; Channel capacity; Direct-sequence code-division multiple-access DS-CDMA ; Frequency-hopped code-division multiple-access FH-CDMA ; computer technology; Data- och systemvetenskap; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : This thesis treats some information-theoretical and coding aspects of communication over multiple-access and fading channels. It consists of a general introduction and seven papers. In code-division multiple-access (CDMA) communication, many users have access to the channel simultaneously. READ MORE

7. 5. Linear Coding, Applications and Supremus Typicality

   Author : Sheng Huang; Mikael Skoglund; Giacomo Como; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear coding; Supremus typicality; Informations- och kommunikationsteknik; Information and Communication Technology; Matematik; Mathematics;

   Abstract : Detta arbete börjar med att presentera en kodningssats gällande linjärkodning över ändliga ringar för kodning av korrelerade diskretaminneslösa källor. Denna sats inkluderar som specialfall motsvarandeuppnåbarhetssatser från Elias och Csiszár gällande linjär kodning överändliga kroppar. READ MORE
