  2. 6. Communication-Efficient Resource Allocation for Wireless Federated Learning Systems

    Author : Chung-Hsuan Hu; Erik G. Larsson; Zheng Chen; Viktoria Fodor; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The training of machine learning (ML) models usually requires a massive amount of data. Nowadays, the ever-increasing number of connected user devices has benefited the development of ML algorithms by providing large sets of data that can be utilized for model training. READ MORE

  4. 7. Spectrum Sensing for Dynamic Spectrum Access in Cognitive Radio

    Author : Inna Valieva; Dag Stranneby; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Abstract. The number of mobile devices is constantly growing, and the exclusivestatic spectrum allocation approach is leading to the spectrum scarcity problem whensome of the licensed bands are heavily occupied and others are nearly unused.Spectrum sharing and opportunistic spectrum access allow achieving more efficientspectrum utilization.

  5. 8. Bluetooth and Wireless Multihop Networks in Industrial Communication Systems

    Author : Urban Bilstrup; Orazio Mirabella; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bluetooth; industrial communication systems; short range devices; wireless multihop networks; wireless sensor networks; real-time communication; resource allocation; Computer engineering; Datorteknik; Datatransmission; Datatransmission;

    Abstract : The objective of this thesis is to investigate the use of short-range wireless communication technology in industrial communication systems where there is a need for guaranteed timely delivery of correct information. Methods for achieving such capability are developed in the context of the physical layer, the data link layer and the application layer. READ MORE

  6. 9. Radio Resource Allocation and Utilization in Multiple Radio Access Networks

    Author : Georgios Koudouridis; Gunnar Karlsson; Frank H. P. Fitzek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Meeting in a sustainable way the demands of an unprecedented explosive growth in the number of connected devices and mobile data traffic, next-generation mobile networks are expected to make flexible use of spectrum and provide higher capacity by a denser deployment of radio access network infrastructure. In addition, the allocation and the utilisation of radio access resources should improve spectrum usage efficiency and keep energy consumption low, implying the capability to effectively exploit the denser deployment of radio accesses and the co-existence of radio accesses belonging to one or multiple radio access technologies.

  7. 10. Systematic Design of Linear Feedback Amplifiers

    Author : Martin Lantz; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Volterra series; dynamic distortion; clipping; nonlinear distortion; systematic design; feedback amplifier; Signalbehandling;

    Abstract : This work adds a quantitative description of distortion to the structured design method of negative-feedback amplifiers. It constitutes a power-series representation of the feedback amplifier, which may include dynamic (memory) effects, where the design parameters appear explicitly. READ MORE
