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

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Machine Learning-based MIMO Indoor Positioning

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Qiyi Chen; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

4. 3. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gustav Lenart; [2023]
   Nyckelord :Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

   Sammanfattning : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. LÄS MER

5. 4. Demonstration of Digital Selective Call spoofing

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Axel Lindbäck; Yamha Javid; [2023]
   Nyckelord :Digital Selective Calling; Software Defined Radio; Spoofing; Cybersecurity; Maritime Communication Systems;

   Sammanfattning : Digital Selective Calling (DSC) is a vital maritime communications and safety system, enabling ships in distress to alert nearby vessels and coast guard stations of their emergency. While DSC is suitable for calling, its technical format is substandard from a cybersecurity perspective. LÄS MER

7. 5. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Filip Palm; [2022]
   Nyckelord :Oceanbird; Sail pressure; KTH; pressure sensor system; Environment; Oceanbird; tryckmätningssystem; miljö; KTH; tryckmätning segel;

   Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER
