1. 1. Life is like a Boxx : How do film production sites affect wireless transmission?

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

   Author : Malin Hall; [2023]
   Keywords : Boxx Atom; wireless transmission; radio shadows; video quality; link budget; signal attenuation; Boxx Atom; trådlös överföring; radioskugga; video kvalitet; länkbudget; signaldämpningg;

   Abstract : Wireless transmission is an everyday part of movie production and a tool many people use in their work. Work, on a movie production, is fast, intense, and varies in geographical location almost on a daily basis (sometimes several locations in a day). Despite this, the stream, the transmission, must hold so the crew can work. READ MORE

3. 2. 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. 3. Decentralized Learning over Wireless Networks with Imperfect and Constrained Communication : To broadcast, or not to broadcast, that is the question!

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Martin Dahl; [2023]
   Keywords : Decentralized Stochastic Gradient Descent; Decentralized Learning; Medium Access Control; Wireless Communications; Machine Learning; Imperfect Communication; Resource-Constrained; Resource Allocation; Scheduling;

   Abstract : The ever-expanding volume of data generated by network devices such as smartphones, personal computers, and sensors has significantly contributed to the remarkable advancements in artificial intelligence (AI) and machine learning (ML) algorithms. However, effectively processing and learning from this extensive data usually requires substantial computational capabilities centralized in a server. READ MORE

5. 4. Beamformed Channel Matrix Positioning using 5G Testbench CSI data with a Deep-Learning Pipeline

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

   Author : Andre Ráth; [2022]
   Keywords : 5G; Deep Learning; Positioning; Channel State Information; CSI; Deep-learning; neural-network; particle-filter; particle; filter; Channel Matrix; Beamformed Channel Matrix; localization; real-world; data-driven; 5G testbench; basestation; Technology and Engineering;

   Abstract : Within the telecommunications industry, a positioning system for estimating user equipment (UE) location using purely information available for the basestation has an enormous number of potential uses. The link between physical position and the network channel state enables potential positioning systems to function by under- standing the network channel state dependency on location, using a model-based, data-based, or a combined approach.

6. 5. Power Focusing with Intelligent Reflective Surfaces for Wireless Indoor Communication Systems

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

   Author : Mingye Gong; [2021]
   Keywords : Intelligent Reflective Surfaces IRS ; 6G; MISO; Wireless Indoor Communication Systems; Technology and Engineering;

   Abstract : Intelligent reflective surfaces (IRS) are envisioned to have a significant number of applications in future wireless network systems by reconfiguring the signal propagation to improve system performance. In particular, the IRS's cell elements can independently reflect the incident signal by tuning its phase and achieving passive beamforming to enhance the received signal of the user equipment.
