  1. 6. Coding Strategies for Compress-and-Forward Relaying

    Författare :Ricardo Blasco-Serrano; Mikael Skoglund; Ragnar Thobaben; Joerg Kliewer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication theory; Telekommunikationsteori;

    Sammanfattning : The deployment of large communication networks with many autonomous devices has opened new possibilities for transmission. In particular cooperation among the different nodes has been identified as an enabling technology to satisfy the increasing demand of resources. LÄS MER

  3. 7. 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

  4. 8. Relaying Protocols for Wireless Networks

    Författare :Majid Nasiri Khormuji; Erik G. Larsson; Christian Ibars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; The relay channel; constellation rearrangement; decode-and-forward; resource allocation; Telecommunication theory; Telekommunikationsteori;

    Sammanfattning : Motivated by current applications in multihop transmission and ad hoc networks, the classical three-node relay channel consisting of a source-destination pair and a relay has received significant attention. One of the crucial aspects of the relay channel is the design of proper relaying protocols, i.e. LÄS MER

  5. 9. Relaying for Timely and Reliable Applications in Wireless Networks

    Författare :Le-Nam Hoang; Elisabeth Uhlemann; Magnus Jonsson; Anthony Ephremides; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Many emerging applications based on wireless networks involve distributed control. This implies high requirements on reliability, but also on predictable maximum delay. Further, for applications, it is vital to use off-the-shelf components, both due to cost constraints and requirements on interoperability with existing networks. LÄS MER

  7. 10. Studies on the Viability of Cellular Multihop Networks with Fixed Relays

    Författare :Bogdan Timus; Jens Zander; Halim Yanikomeroglu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : The use of low cost fixed wireless relays has been proposed as a way to deploy high data-rate networks at an affordable cost. During the last decade, significant academic and industrial research has been dedicated to relays. Protocol architectures for cellular-relaying networks are currently considered for standardization as part of both IEEE 802. LÄS MER
