  4. 3. Throughput Analysis of Interfering Packet Radio Networks

    Författare :André Stranne; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; energy; collision; packet length; frequency hopping; throughput; successful packet reception probability; heterogeneous packet radio networks; interference analysis;

    Sammanfattning : In this thesis, a probabilistic framework is presented and used for analysis of the throughput of interfering packet-based radio networks, referred to as packet radio networks (PRNs). Previous research on the performance of PRNs covers a wide variety of systems and aspects in varying levels of detail. LÄS MER

  5. 4. Applications of Resource Optimization in Wireless Networks

    Författare :Patrik Björklund; Peter Värbrand; Mikael Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; telecommunication; scheduling; gsm; wcdma; ad-hoc; frequency planning; Telecommunication; Telekommunikation;

    Sammanfattning : The demand for wireless communications is increasing every year, but the available resources are not increasing at the same rate. It is very important that the radio resources are used in an efficient way allowing the networks to support as many users as possible. LÄS MER

  7. 5. Analysis and Design of DLL-Based Frequency Synthesizers for Ultra-Wideband Communication

    Författare :Amin Ojani; Atila Alvandpour; Behzad Mesgarzadeh; Per Larsson-Edefors; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Ever increasing demand for high speed transmission of large data between the electronic devices within a wireless personal area network has been motivating the development of the appropriate wireless standards. Ultra-wideband (UWB) communication employs the unlicensed frequency spectrum of 3.1 ‒ 10. LÄS MER
