  1. 6. 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. 7. 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

  4. 8. Radio signal detection and localisation for uncovering unauthorised signals in an examination environment

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Marcus Adler; Otto Lundin; Lam Nguyen; Nour Alddin Taki; [2021-09-14]
    Keywords : Cheating; Anti-cheat; Cheat-detection; Radio signal detection; Multilateration; SDR; ADALM-PLUTO; Signal localisation;

    Abstract : Examination is a fundamental part of education, both for students and institutions. Cheating on exams is something educational institutions are trying to reduce. One form of cheating is the use of a mobile phone to live-stream the exam to pass the test. READ MORE

  5. 9. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.

  6. 10. Audio-based Motion Detection

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

    Author : Gopal Gomatam; Filip Dujmic; [2021]
    Keywords : sonar; motion detection; audio frequencies; audio processing; Technology and Engineering;

    Abstract : Motion detection is an essential technology and it has numerous use-cases, such as security tracking, automated door opening systems, and IP cameras. Commonly, passive infrared sensors or radio frequency sensors are used for motion detection. However, this thesis focuses on performing motion detection using existing hardware at audio frequencies.
