1. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices.

2. Deep Learning for the prediction of RASER-MRI profiles
Master-uppsats, Linköpings universitet/Medie- och InformationsteknikSammanfattning : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. LÄS MER
3. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. LÄS MER
4. Formation Control of UAVs for Positioning and Tracking of a Moving Target
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : The potential of Unmanned Aerial Vehicles (UAVs) for surveillance and military applications is significant — with continued technical advances in the field. The number of incidents where UAVs have intruded into unauthorized areas has increased in recent years and armed drones are commonly used in modern warfare. LÄS MER
5. Backscatter Communications for 6G
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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.
