  1. 1. Coding Schemes for Relay Networks

    Författare :Majid Nasiri Khormuji; Mikael Skoglund; Gerhard Kramer; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

    Sammanfattning : Relay networks and cooperative transmission have spurred considerable interest in recent years, promising performance improvements in, e.g., system capacity, robustness and transmission rate. LÄS MER

  4. 3. Improved Techniques for Retransmission and Relaying in Wireless Systems

    Författare :Chaitanya V. K. Tumula; Erik G. Larsson; Tobias J. Oechtering; Linköpings universitet; []
    Nyckelord :Hybrid-ARQ; relaying schemes; superposition coding; 3GPP- LTE; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The last three decades have seen significant advances in the wireless communication field. As the data rates of wireless systems are increasing, the demand for mobile services also is increasing rapidly. Like other natural resources, radio spectrum suitable for mobile wireless communications is also limited. LÄS MER

  5. 4. Relaying for Industrial Wireless Networks

    Författare :Svetlana Girs; Fredrik Brännström; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : The interest in wireless technology for industrial applications has increased dramatically over the last few years. Wireless communication can reduce cost and complexity, enable mobility and provide much higher flexibility than its wired counterparts. LÄS MER

  7. 5. 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
