1. 6. AI Based Methods for Matrix Multiplication in High Resolution Simulations of Radio Access Networks

   Master-uppsats, KTH/Matematisk statistik

   Författare :Marcus Johnson; Herman Forslund; [2023]
   Nyckelord :Product-Quantization; MADDNESS; Radio Access Networks; Channel Estimation; MIMO; Approximate Matrix Multiplication; Pruduktkvantisering; MADDNESS; RAN; MIMO; Approximativa matrismultiplikation;

   Sammanfattning : The increasing demand for mobile data has placed significant strain on radio access networks (RANs), leading to a continuous need for increased network capacity. In keeping with that, a significant advancement in modern RANs is the ability to utilize several receivers and transmitters, to allow for beamforming. LÄS MER

5. 9. Development of a real-time navigation and collisionavoidance system for an autonomous naval rover : A Contribution to the Environmental Initiative for Flexible andReal-time Water Monitoring of the CatFish team

   Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Esmee Tackx; [2023]
   Nyckelord :;

   Sammanfattning : This thesis explores the design and optimisation of a sensor system for real-time position determination of the Fish component in the CatFish naval drone and the development of a sonar sensor system for accurate object localisation and safe navigation in dynamic and uncertain underwater conditions. Through comprehensive experimentation and analysis, this thesis demonstrates the effectiveness of the proposed sensor system and sonar sensing system in enhancing underwater navigation and obstacle avoidance capabilities.

7. 10. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ashray Ugle; [2023]
   Nyckelord :Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

   Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.
