  1. 16. Resource Allocation for Federated Learning over Wireless Networks

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Fredrik Jansson; [2022]
    Keywords : Federated Learning; Neural Networks; Channel Model; Scheduling; Compression; Distributed Data;

    Abstract : This thesis examines resource allocation for Federated Learning in wireless networks. In Federated learning a server and a number of users exchange neural network parameters during training. READ MORE

  3. 17. Portable HF Antennas for Concurrent Multiband Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sambhav Malhotra; [2022]
    Keywords : Antenna; HF; Skywave Propogation; Multiband;

    Abstract : Current HF communication systems are confined to transmit in relatively narrow frequency band of a few 100 kHz at the time. The problems with limited bandwidth accumulate in HF-networks with multiple links and such networks are therefore hardly “internet capable” today. READ MORE

  4. 18. Dual-polarized geodesic lens in sub-THz

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wenfu Fu; [2022]
    Keywords : beam scanning; dual polarization; fully metallic; geodesic lens; Luneburg lens antenna; THz; strålskanning; korspolarisering; fullt metallisk; geodetisk lins; Luneburg linsantenn; THz;

    Abstract : In the sub-THz frequency range, the geodesic lens can realize low losses and beam scanning capability with high gain and high aperture efficiency due to its fully metallic property and rotational symmetry. Therefore, in high-frequency applications, a geodesic lens is considered a more promising solution in comparison to phased arrays or other beamforming techniques. READ MORE

  5. 19. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  6. 20. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Linus Holgersson; [2022]
    Keywords : Phosphorus; Two-stage ditch; Equilibrium phosphate concentration; Phosphorus retention; Eutrophication; Soluble reactive phosphorus;

    Abstract : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. READ MORE
