  1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

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

    Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  2. 2. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Anna Brandt; [2022]
    Keywords : Physics and Astronomy;

    Abstract : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. READ MORE

  3. 3. An amplitude modulated laser rangefinder : electronic circuit design and implementation

    University essay from Uppsala universitet/Signaler och system

    Author : Fazel Naser; Stefan Morin; [2022]
    Keywords : Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

    Abstract : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. READ MORE

  4. 4. 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

  5. 5. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Elias Arnqvist; [2022]
    Keywords : Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

    Abstract : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. READ MORE
