1. 16. Backscatter Communications for 6G

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

   Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Keywords : Technology and Engineering;

   Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

3. 17. Sound Source Localization for an Urban Outdoor Setting : A Systematic Review

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

   Author : Anna Malmgren; [2022]
   Keywords : sound source localization; outdoor localization; state of the art SSL;

   Abstract : Sound source localization (SSL) is a broad field, with many important application areas. In outdoor environments SSL systems can, among other things, be used to increase citizens’ safety by detecting and locating abnormal sounds such as gunshots or screams. READ MORE

4. 18. Localization For AutonomousDriving using Statistical Filtering : A GPS aided navigation approach with EKF and UKF

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

   Author : Devrat Singh; [2022]
   Keywords : Land Vehicle Localization; Sensor Fusion; GNSS-INS Fusion; UKF; EKF;

   Abstract : A critical requirement for safe autonomous driving is to have an accurate state estimate of thevehicle. One of the most ubiquitous yet reliable ways for this task is through the integrationof the onboard Inertial Navigation System (INS) and the Global Navigation Satellite System(GNSS). READ MORE

5. 19. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

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

   Author : Rungeng Xu; [2022]
   Keywords : E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

   Abstract : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. READ MORE

6. 20. Improving deep learning assistedfar-field electromagnetic sidechannelattacks on AES : Effects on attack efficiency from using additive noise and otherdata augmentation techniques

   University essay from KTH/Mekatronik

   Author : Axel Zedigh; [2022]
   Keywords : ;

   Abstract : Profiled side-channel attacks on hardware implemented cryptographic algorithms have been a well-researched topic for the past two decades and many countermeasures against these attacks have been proposed and adopted by the industry. Recently, a new form of far field EM side channel called "screaming channel attacks" have been highlighted. READ MORE
