  1. 1. Source-Channel Coding in Networks

    Författare :Niklas Wernersson; Mikael Skoglund; Geoffrey Chan; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Sammanfattning : 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. LÄS MER

  3. 2. Coding, Computing, and Communication in Distributed Storage Systems

    Författare :Majid Gerami; Ming Xiao; Camilla Hollanti; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 3. Source and Channel Coding for Compressed Sensing and Control

    Författare :Amirpasha Shirazinia; Mikael Skoglund; Pier Luigi Dragotti; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Source coding; quantization; channel coding; compressed sensing; control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Rapid advances in sensor technologies have fueled massive torrents of data streaming across networks. Such large volume of information, indeed, restricts the operational performance of data processing, causing inefficiency in sensing, computation, communication and control. LÄS MER

  5. 4. Communication With Reconstruction and Privacy Constraints

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

    Sammanfattning : 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. LÄS MER

  7. 5. Low-delay sensing and transmission

    Författare :Johannes Kron; Mikael Skoglund; Tor Ramstad; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; distributed source coding; estimation; quantization; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis studies cooperative sensing and transmission in the context ofwireless sensor networks (WSNs). We especially focus on two means of cooperative sensing and transmission, namely, distributed source coding and relaying. LÄS MER
