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

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

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

   Abstract : 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. READ MORE

3. 2. Peripheral Nervous Network Simulator : A Computer Networks approach

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Baha Eddine Hmidi; [2022]
   Keywords : peripheral nervous system; nerve damage; signal blockage; node; graph; network emulator;

   Abstract : The peripheral nervous system can be seen as a huge network of neurons that prop-agates signals across the human body. In fact, as seen in [1] , "All the information streaming in the peripheral nervous system (PNS) is transmitted along axons byelectro-chemical signals called action potentials". READ MORE

4. 3. RayTracing Analysis and Simulator Design of Unmanned Aerial Vehicle Communication and Detection System in Urban Environment

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

   Author : Jie Huang; [2022]
   Keywords : Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

   Abstract : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. READ MORE

5. 4. Ultra-wideband location tracking of mobile devices

   University essay from Uppsala universitet/Signaler och system

   Author : Daniel Hietarinta; [2022]
   Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

   Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

6. 5. Human Body Presence Detection in Water Environments Using Pulse Coherent Radar

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Jens Moths; Frotan Frotan; [2022]
   Keywords : presence detection; dead man s grip; micro; mmwave; radar; radome; a111; acconeer; radinn; direct leakage; electric surfboard; närvaro detektering; dödmansgrepp; micro; mmwave; radar; radome; a111; acconeer; radinn; direktläckage; elektrisk surfbräda;

   Abstract : New technology in radar opens up new possibilities for cheap and easily integrated human body presence detection. In this work, we aim to make a proof of concept that replaces the "dead man’s grip" on an electric surfboard with a more convenient wireless system based on micro radars. READ MORE
