1. 1. Performance Evaluation of LoRa networks for Air-to-Ground Communications

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

   Författare :Kiana Khorsandi; Sareh Jalalizad; [2023]
   Nyckelord :IoT; LPWAN; LoRaWan; UAV; LAP; Bit error rate; Line of sight;

   Sammanfattning : The current focus on the Internet of Things (IoT) has led to the emergence of many network scenarios with unlimited use cases, including smart homes, smart cities, smart agriculture, and more. Unmanned aerial vehicles (UAVs), also known as drones, have become increasingly popular due to their versatility and ability to collect and transmit data through various sensors and cameras. LÄS MER

3. 2. Machine Learning-based MIMO Indoor Positioning

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Qiyi Chen; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

4. 3. Development of AI/ML Methods for Advanced Device Localization in Beyond 5G Systems

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Eros Iván Costa Andrés; Jon Aizkorreta Carro; [2023]
   Nyckelord :Artificial Intelligence; localization; IIoT devices; Python; radio signals; 5G; 3GPP; Technology and Engineering;

   Sammanfattning : This master thesis aims to investigate the positioning accuracy improvements of device localization by the implementation of AI/ML functionalities. In this project, we use the fifth-generation(5G) New Radio (NR) system and focus on indoor factories. LÄS MER

5. 4. Virtual alignment of real-world objects

   Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Tommy Ekberg; William Ekelund; [2023]
   Nyckelord :Ultra-wideband; Indoor positioning system; Document survey; NLoS; Multisensor; Trilateration; Localization;

   Sammanfattning : High accuracy localization of objects is a crucial function for many modern applications, such as virtual and augmented reality, robotics, and self-driving cars, among others. This requires determining precise location of objects indoors, which is a challenging task. LÄS MER

7. 5. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Andre Ráth; [2022]
   Nyckelord :5G; Deep Learning; Positioning; Channel State Information; CSI; Deep-learning; neural-network; particle-filter; particle; filter; Channel Matrix; Beamformed Channel Matrix; localization; real-world; data-driven; 5G testbench; basestation; Technology and Engineering;

   Sammanfattning : Within the telecommunications industry, a positioning system for estimating user equipment (UE) location using purely information available for the basestation has an enormous number of potential uses. The link between physical position and the network channel state enables potential positioning systems to function by under- standing the network channel state dependency on location, using a model-based, data-based, or a combined approach.
