    Abstract : As an engineer and researcher, I have been dealing with the research, standardization and industrial-ization of wireless communication systems since the late 90’s. Specifically, I have been witnessing andcontributing to the evolution of the 3rd, 4th and currently to the 5th generation of cellular networks. READ MORE

  5. 3. Distribution Preserving Quantization

    Author : Minyue Li; W. Bastiaan Kleijn; Jan Østergaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. READ MORE

  6. 4. Cost Effective Deployment Strategies for Heterogenous Wireless Networks

    Author : Klas Johansson; Jens Zander; Preben Mogensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Wireless access to the Internet is expected to be very valuable for both individuals and the society. However, advances in transmission technology alone may not be sufficient to support the anticipated demand for higher data rates and greater traffic volumes. READ MORE

  7. 5. Cooperative and non-cooperative wireless access : Resource and infrastructure sharing regimes

    Author : Johan Hultell; Jens Zander; Cristina Comaniciu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radio resource managment competition cooperation game theory; Telecommunication; Telekommunikation;

    Abstract : Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. READ MORE
