1. 1. 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

3. 2. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

   University essay from KTH/Fastigheter och byggande

   Author : Adrien Bardou; [2021]
   Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

   Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.

6. 5. Wireless electrocardiogram based on ultra-wideband communications

   University essay from Uppsala universitet/Signaler och System

   Author : Maria Toll; [2019]
   Keywords : UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

   Abstract : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).
