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

   Author : Qinglin Zou; [2023]
   Keywords : Joint communication and sensing; Cell-free massive MIMO; Swerling models; Distributed Sensing; Gemensam kommunikation och avkänning; Cellfri massiv MIMO; Swerling modeller; Distributed Sensing;

   Abstract : Joint Communication and Sensing (JCAS) technology enables the sharing of infrastructure, resources, and signals between communication and sensing. However, studying the performance and algorithms using appropriate target reflectivity models for detection poses a significant challenge. READ MORE

3. 2. Machine Learning-based MIMO Indoor Positioning

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

   Author : Qiyi Chen; [2023]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. Real-time remote processing enabled by high speed Ethernet

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

   Author : Dumitra Iancu; Lina Tinnerberg; [2023]
   Keywords : Large Intelligent Surfaces; Deep Neural Networks; FPGA; VHDL; Ethernet; Technology and Engineering;

   Abstract : A growing trend within the technologies acting as enablers for 6g, such as Massive MIMO and Large Intelligence Surfaces, is benefiting from both the communication and the positioning aspects that they can provide. As these kinds of systems are employing a large number of arrays which provide high amounts of data, a distributed hardware approach having near-antenna processing is explored in this work.

5. 4. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

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

   Author : Frans Nyberg Zou; [2022]
   Keywords : 6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

   Abstract : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. READ MORE

6. 5. Access Point Selection and Clustering Methods with Minimal Switching for Green Cell-Free Massive MIMO Networks

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

   Author : Qinglong He; [2022]
   Keywords : Cell-free massive MIMO; multi-objective optimization; deep reinforcement learning; AP switch ON OFF; energy efficiency; Cellfri massiv MIMO; multiobjektiv optimering; djup förstärkningsinlärning; AP switch ON OFF; energieffektivitet;

   Abstract : As a novel beyond fifth-generation (5G) concept, cell-free massive MIMO (multiple-input multiple-output) recently has become a promising physical-layer technology where an enormous number of distributed access points (APs), coordinated by a central processing unit (CPU), cooperate to coherently serve a large number of user equipments (UEs) in the same time/frequency resource. However, denser AP deployment in cell-free networks as well as an exponentially growing number of mobile UEs lead to higher power consumption. READ MORE
