  1. 1. Coding Schemes for Relay Networks

    Author : Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  2. 2. Decentralized Network Optimization in Wireless Networks

    Author : Yuzhe Xu; Carlo Fischione; Tommaso Melodia; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : Distributed estimation and distributed resource allocation are two important services in future cyber-physical wireless networks. The former aims to estimate, or track, physical variables of a phenomenon monitored by a wireless network, whereas the latter aims to optimally assign the limited communication resources to the nodes in a wireless network.

  3. 3. Transformation and Symbolic Calculations in Filtering and Control

    Author : Ke Wang-Chen; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with several aspects of optimal control and filtering problems. A fundamental problem in the optimal control theory is the design of a regulatorfora linear system which minimizes a quadratic cost function characterizing the control effort and the deviations of the system from the ideal operation.

  4. 4. Device-to-Device Communication in Future Cellular Networks : Resource allocation and mode selection

    Author : Demia Della Penda; Mikael Johansson; Ioannis Krikidis; KTH; []
    Keywords : Wireless communication; cellular networks; device to device; resource management; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The widespread use of smart devices and mobile applications is leading to a massive growth of wireless data traffic. Supporting the upcoming demands of data volume, communication rate, and system capacity requires reconsideration of the existing network architecture. READ MORE

  5. 5. Low-delay sensing and transmission

    Author : Johannes Kron; Mikael Skoglund; Tor Ramstad; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE
