  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. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : David Rydgård; [2023]
    Keywords : Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

    Abstract : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. READ MORE

  3. 3. Functional Bio-based Copolyesters: Properties and Abilities

    University essay from KTH/Fiber- och polymerteknologi

    Author : Fika Andriani; [2022]
    Keywords : Ring-opening copolymerization; epoxide; anhydride; crosslinked; degradation; Ringöppningssampolymerisation; epoxid; anhydrid; tvärbundet; nedbrytning;

    Abstract : Genom ringöppningssampolymerisation av utvalda epoxider och anhydrider möjliggjordes en enkel strategi för att syntetisera funktionella sampolymerer. Sampolymererna hade förmågan att bilda tvärbundna material, och var dessutom benägna för både hydrolytisk och enzymatisk nedbrytning. READ MORE

  4. 4. Unsupervised Anomaly Detection and Root Cause Analysis in HFC Networks : A Clustering Approach

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

    Author : Povel Forsare Källman; [2021]
    Keywords : Anomaly Detection; Root Cause Analysis; Cluster Analysis; k- means; Self- Organizing Map; Gaussian Mixture Model; Dimensionality Reduction; Principal Component Analysis; Hybrid Fiber- Coaxial Network.; Anomalidetektering; Rotfelsanalys; Klusteranalys; k- means; Self- Organizing Map; Gaussian Mixture Model; Dimensionsreducering; Principal Component Analysis; Hybrid Fiber Coax- nät.;

    Abstract : Following the significant transition from the traditional production industry to an informationbased economy, the telecommunications industry was faced with an explosion of innovation, resulting in a continuous change in user behaviour. The industry has made efforts to adapt to a more datadriven future, which has given rise to larger and more complex systems. READ MORE

  5. 5. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

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

    Author : Sergio Steven Gutierrez; [2020]
    Keywords : QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Abstract : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. READ MORE
