  1. 1. Applications of Resource Optimization in Wireless Networks

    Författare :Patrik Björklund; Peter Värbrand; Mikael Johansson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  2. 2. Optimization Models and Methods for Telecommunication Networks using OSPF

    Författare :Peter Broström; Michal Pióro; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Telecommunication; OSPF; LP-duality; Polynomial methods; MATHEMATICS; MATEMATIK;

    Sammanfattning : The routing in OSPF Telecommunication networks is determined by computing shortest paths with respect to link weights set by the network operator. All shortest paths to a destination are used by the routers when traffic is routed, and the routers split the traffic evenly when alternative shortest paths exist. LÄS MER

  3. 3. Radio Frequency Power Amplifiers : Behavioral Modeling, Parameter Reduction, and Digital Predistortion

    Författare :Magnus Isaksson; Peter Händel; José C. Pedro; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Telecommunication; Telekommunikation; Electronics; Elektronik;

    Sammanfattning : This work considers behavioral modeling, parameter-reduction, and digital predistortion of radio frequency power amplifiers. Due to the use of modern digital modulation methods, contemporary power amplifiers are frequently subjected to signals characterized by considerable bandwidths and fast changing envelopes. LÄS MER

  4. 4. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation

    Författare :Ellen Grumert; Jan Lundgren; Andreas Tapani; Wilco Burghout; Statens väg- och transportforskningsinstitut; []
    Nyckelord :Variable speed limit; Traffic; Micro; Simulation; Data exchange; Telecommunication; Vehicle; Transport infrastructure; Intelligent transport system; In vehicle information; 23 Road: ITS och traffic; 23 Road: ITS och traffic; 25 Road: Traffic theory; 25 Road: Traffic theory;

    Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER

  5. 5. The Role of History in the Modern Company : Ericsson and the Past

    Författare :Brita Lundström; KTH; []
    Nyckelord :industrial history; history of technology; cultural history; use of history; business history; corporate identity; factory buildings; modernism; telecommunication; Ericsson; Telefonplan Midsommarkransen ; Kista; Stockholm; National Museum of Science;

    Sammanfattning : The overall purpose of the thesis is to discuss the presenceand influence of the commercial use of history in modernindustrial companies and history's role in creating andchanging corporate identity. More specifically the aim is toanalyse the way the Swedish telecom company Ericsson has madeuse of its history at three different occasions. LÄS MER
