1. 21. Efficient Coding Techniques for Networks & Channels with Transmission Errors

   Författare :Ming Xiao; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 22. Spaces of Writing History in the Postcolonial City : Edits, Erasures, Inscriptions

   Författare :Suha Hasan; Maria Håkansson; Catharina Gabrielsson; Stephen Ward; Jane Jacobs; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; Urban and Regional Studies; Urbana och regionala studier;

   Sammanfattning : The search for a pre-colonial identity has occupied post-colonial cities since independence, becoming intertwined with modern nation-building projects. Consequently, an active agenda of reframing heritage has emerged that is strongly connected to the process of revisiting and rewriting the past. LÄS MER

4. 23. Wireless Broadcasting with Network Coding

   Författare :Lu Lu; Lars Kildehöj Rasmussen; Giuseppe Durisi; KTH; []
   Nyckelord :wireless broadcasting; relay-aided system; systematic binary deterministic rateless codes; random network coding; instantaneously decodable network coding;

   Sammanfattning : Wireless digital broadcasting applications such as digital audio broadcast (DAB) and digital video broadcast (DVB) are becoming increasingly popular since the digital format allows for quality improvements as compared to traditional analogue broadcast. The broadcasting is commonly based on packet transmission. LÄS MER

5. 24. Capabilities of Convolutional Codes: Unequal Error Protection and More

   Författare :Victor Pavlushkov; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; systemteori; Informatik; Informatics; systems theory; woven codes; unequal error protection; active input-distance; active output-distance; maximum slope; active distances; Convolutional codes; error-correcting capability;

   Sammanfattning : Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. LÄS MER

7. 25. Coding, Computing, and Communication in Distributed Storage Systems

   Författare :Majid Gerami; Ming Xiao; Camilla Hollanti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coding; Distributed Systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Conventional studies in communication networks mostly focus on securely and reliably transmitting  data from a source node (or multiple source nodes) to multiple destinations. A more general problem appears when the destination nodes are interested in obtaining  functions of the data available in distributed source nodes. LÄS MER
