2. 1. Control and Communication with Signal-to-Noise Ratio Constraints

   Author : Erik Johannesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time coding; SNR; Causal coding; AWN channel; AWGN channel; Remote source; Networked control; Control over channel; Convex optimization; Wiener filter;

   Abstract : This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. READ MORE

   Abstract : Networked control over wireless networks is of growing importance in many application domains such as industrial control, building automation and transportation systems. Wide deployment however, requires systematic design tools to enable efficient resource usage while guaranteeing close-loop control performance. READ MORE

5. 3. On the Design of Error Control Coding for Wireless Communication Systems

   Author : Carl Fredrik Leanderson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; joint source-channel decoding; Electrical engineering; Elektroteknik; a posteriori probability; soft decoding; list sequence decoding; incremental redundancy; retransmission; low-rate; parallel concatenated; convolutional codes; Turbo codes; Wireless; error correction;

   Abstract : New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. READ MORE

6. 4. Coding, Computing, and Communication in Distributed Storage Systems

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

   Abstract : 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. READ MORE

7. 5. Wireless Broadcasting with Network Coding

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

   Abstract : 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. READ MORE
