  2. 1. On Performance Analysis of Retransmission Schemes with Fading Channels

    Author : Peter Larsson; Lars Kildehøj Rasmussen; Mikael Skoglund; Leszek Szczecinsky; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic repeat request; ARQ; hybrid-arq; retransmission schemes; Telecommunication; Telekommunikation;

    Abstract : Future wireless communication systems and services bring increased performance demands, with respect to data-rate(s), reliable communication, (stochastic) real-time guarantees, and more. In this context, not only new communication schemes are needed, but also more capable performance analysis methods are essential. READ MORE

    Author : Mikael Gidlund; Geir E Øien; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

    Abstract : High data-rate wireless access systems are currently under discussion since the demand for wireless multimedia communication is rapidly increasing due to strong advances in wireless Internet services. Reliable high-speed data communications is one of the major challenges with regards to harsh conditions. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. A Study of Partially Reliable Transport Protocols for Soft Real-Time Applications

    Author : Karl-Johan Grinnemo; Anna Brunström; Bengt Ahlgren; Karlstads universitet; []
