    Sammanfattning : The last two decades have witnessed the birth of revolutionary technologies in data communications including wireless technologies, System on Chip (SoC), Multi Processor SoC (MPSoC), Network on Chip (NoC), and more. At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimediaservices and biomedical applications. LÄS MER

  3. 3. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications

    Författare :E. Martin I. Gustafsson; Ana Rusu; Georges Gielen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Circuits; Analog to Digital Converters; Wireless communication; Electronics Engineering; Electrical Engineering; Electronics; Elektronik;

    Sammanfattning : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.

  4. 4. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies

    Författare :Sten Gunnarsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image reject mixer; Broadband wireless communication; Single-chip; Multifunctional; Mixer; Balanced resistive mixer; GaAs; Dual-quadrature mixer; 60 GHz; Receiver; pHEMT; MMIC; High data-rate; Double balanced Gilbert mixer; mHEMT; Transmitter; V-band;

    Sammanfattning : In recent years, the 60 GHz band has gained increased academic and commercial interest mainly due to the relative large amount of license free and little used frequency spectrum located in vicinity of 60 GHz. The exact locations of these free frequency bands varies locally but the 5962 GHz band overlap around the world and is therefore a true world wide license free band. LÄS MER

  5. 5. Performance Analysis in Wireless HetNets: Traffic, Energy, and Secrecy Considerations

    Författare :Georgios Smpokos; Nikolaos Pappas; Vangelis Angelakis; Qinghua Wang; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To this day, most of the communication networks are characterized by a "monolithic" operating approach. Network elements are configured and operate without any reconfiguration for long time periods. Softwarization, whereby dedicated elements are being replaced by more general-purpose devices, has been lately challenging this existing approach. LÄS MER
