2. 6. Variation-Aware System Design Simulation Methodology for Capacitive BCC Transceivers

   Author : Muhammad Irfan Kazim; Jacob Wikner; Svante Signell; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Capacitive body coupled communication (BCC), frequency range 500 kHz to 15 MHz, is considered an emerging alternate short range wireless technology which can meet the stringent low power consumption (< 1 mW) and low data rate (< 100 kbps) requirements for the next generation of connected devices for applications like internet-of-things (IoT) and wireless sensor network (WSN). But a reliable solution for this mode of communication covering all possible body positions and maximum communication distances around the human body could not be presented so far, despite its inception around 20 years back in 1995.

4. 7. Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach

   Author : Fredrik Harrysson; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel model; MIMO; multiple antennas terminal; propagation; user interaction; vehicular channel; diversity; spatial multiplexing; channel measurement;

   Abstract : For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. READ MORE

5. 8. Fat-IBC : A New Paradigm for Intra-body Communication

   Author : Noor Badariah Asan; Robin Augustine; Thiemo Voigt; Ali Khaleghi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fat-Intrabody Communication; Fat Tissue; Microwave; Propagation; Data Packet Reception; Ex-vivo; Phantom; Communication; Reliability; Implants; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Abstract : In the last two decades, a significant development in the field of medical technology occurred worldwide. This development is characterized by the materialization of various body implants and worn devices, that is devices attached to the body. READ MORE

6. 9. Channel Gain Prediction for Cooperative Multi-Agent Systems

   Author : Markus Fröhle; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; channel prediction; multi-agent systems; spatial correlation; wireless ad-hoc networks; parameter learning; distributed algorithms;

   Abstract : In a cooperative multi-agent system (MAS), agents communicate with each other using the wireless medium. As agents move in the environment in order to fulfill the MAS' higher level task, their location changes and so does the wireless communication channel they experience. READ MORE

7. 10. Vehicular Communication in Obstructed and Non Line-of-Sight Scenarios

   Author : Dimitrios Vlastaras; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-to-Vehicle Communications; Channel Modeling; Vehicular Communication; Truck Obstruction; Channel Emulation; Radar; 802.11p; Car; Truck; Accident Avoidance; V2V; V2I; C2C; V2X;

   Abstract : Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives. READ MORE
