2. 1. Coding Schemes for Relay Networks

   Author : Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Relay networks; capacity; decode-and-forward; amplify-andforward; compress-and-forward; nonlinear relaying; noisy network coding; hybrid relaying; Telecommunication; Telekommunikation;

   Abstract : Cooperative communications by pooling available resources—for example, power and bandwidth—across the network, is a distributed solution for providing robust wireless transmission. Motivated by contemporary applications in multi-hop transmission and ad hoc networks, the classical three-node relay channel (RC) consisting of a source–destination pair and a relay node has received a renewed attention.

4. 2. 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

5. 3. Communication With Reconstruction and Privacy Constraints

   Author : Kittipong Kittichokechai; Mikael Skoglund; Tobias J. Oechtering; Sennur Ulukus; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source coding; channel coding; information privacy; physical layer security; action; side information; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Communication networks are an integral part of the Internet of Things (IoT) era. They enable endless opportunities for connectivity in a wide range of applications, leading to advances in efficiency of day-to-day life. While creating opportunities, they also incur several new challenges. READ MORE

6. 4. On Secure and Sequential Source Coding

   Author : Hamid Ghourchian; Mikael Skoglund; Tobias J. Oechtering; Michèle Wigger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Secure source coding is an important research area in recent years as it deals with the problem of transmitting sensitive information over insecure channels while protecting it from unauthorized access. This is particularly relevant in the context of modern communication systems where the data transmitted is often sensitive in nature and the threat of eavesdropping or data breaches is high.

7. 5. Stereophonic Acoustic Echo Cancellation: Theory and Implementation

   Author : Peter Eneroth; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stereophonic Acoustic Echo Cancellation; Filterbank; Two-Channel Fast RLS; Two-Channel Frequency-Domain Adaptive filtering; NLMS; Electronics and Electrical technology; Audio Coding; Elektronik och elektroteknik; Signal processing; Signalbehandling; Subband;

   Abstract : The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. READ MORE
