1. 1. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

   Författare :Zhenyu Li; [2023]
   Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

4. 3. MmWave Radar-based Deep Learning Collision Prediction

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

   Författare :Taylor Lauren V'dovec; [2023]
   Nyckelord :collision prediction; mmWave radar; deep learning; variational autoencoder VAE ; drone; autonomous navigation; kollisionsprognos; mmWave radar; djupinlärning; variational autoencoder VAE ; drönare; autonom navigation;

   Sammanfattning : Autonomous drone navigation in classical approaches typically involves constructing a map representation and employing path planning and collision checking algorithms within that map. Recently, novel deep learning techniques combined with depth camera observations have emerged as alternative approaches capable of achieving comparable collision-free performance. LÄS MER

5. 4. Full Duplex for Joint Communication and Sensing in 6G.

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Soumya Jandhyala; [2023]
   Nyckelord :;

   Sammanfattning : Background: 6G mobile communication is one of the fastest-growing fields of technology. The present 5G mobile networks will not be adequate to meet society’s wireless connectivity demand in the near to mid-term future. A new generation of wireless mobile networks has to be developed to address this demand. LÄS MER

7. 5. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC

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

   Författare :Viktor Lewin; [2023]
   Nyckelord :Phase-locked loop; PLL; DPLL; Frequency Synthesis; TDC; PFD; Technology and Engineering;

   Sammanfattning : This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. LÄS MER
