  1. 1. Power Estimation Tool for Digital Front-End 5G Radio ASIC

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Rajnandini Bhutada; [2023]
    Keywords : 5G; ASIC; DFE; Carrier Aggregation; Digital Pre-Distortion; Downlink; Uplink; Power Consumption; Power Model; Yield Analysis.;

    Abstract : Application Specific Integrated Circuits (ASICs) are critical to delivering on 5G’s promises of high speed, low latency, and expanded capacity. Digital Front-End (DFE) ASICs are particularly important components because they enhance crucial signal processing activities. READ MORE

  3. 2. Deep Learning for Predicting Electrical Power in 5G

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

    Author : Robert Mellberg; [2022]
    Keywords : 5G; Deep learning; Machine learning; Predictions; Electrical power; 5G; Djupinlärning; Maskininlärning; Förutsägelser; Elektrisk effekt;

    Abstract : 5G is currently being implemented around the world. A way to save resources in 5G could be to have several sector carriers sharing one power source. This requires being able to predict the electrical power of the sector carriers to make sure they do not exceed the capability of the power source. READ MORE

  4. 3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

  5. 4. Technologies and Evaluation Metrics for On-Board Over the Air Control

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Aneysha Datta; [2022]
    Keywords : Wireless; Performance Metrics; WAVE; DMG; Intra-Vehicular Communication; BER; Simulink; Model-Based Design;

    Abstract : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. READ MORE

  6. 5. Overcoming Inter-carrier-interference in OFDM System

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Fukang Guo; Luoan Lu; [2021]
    Keywords : ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

    Abstract : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. READ MORE
