1. 6. Design and Implementation of an Efficient Intrusion Response System for 5G RAN Baseband Units

   University essay from Linköpings universitet/Databas och informationsteknik

   Author : Mirna Ghazzawi; Adil Imran; [2023]
   Keywords : Intrusion Response System; Security; OSSEC; Radio Access Network; Baseband Units;

   Abstract : The 5G Radio Access Network (RAN) is a critical system that must be secured against potential attacks, particularly its Base-Band Unit (BBU), which is a common target for intrusions. Ericsson, which is a big provider of such systems, has placed significant emphasis on implementing Intrusion Detection Systems (IDS) to detect threats. READ MORE

3. 7. 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.

4. 8. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Author : Sai Chetan Poluri; Tejaswi Dunuka; [2023]
   Keywords : 5G and 6G Communications; FMCW; GNU Radio; ISAC; OFDM; SDR; Sensing; JSAC;

   Abstract : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. READ MORE

5. 9. Measuring Sprint Speed with Ultra-wideband Technology

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

   Author : Johannes Arenander; [2023]
   Keywords : Speed; Sprint; Ranging; Ultra-wideband; Hastighet; Sprint; Distansmätning; Ultrabredband;

   Abstract : Sprinting can be an important ability in sports, and there are many methods for measuring sprint performance. Two common methods are hand-held timing and fully automatic timing systems. However, hand-held timing is inaccurate due to reaction time, and fully automatic timing can be impractical since it involves complex equipment. READ MORE

6. 10. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

   Author : Jessica Ye; Johan Lesko; [2023]
   Keywords : ;

   Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE
