  1. 1. Joint CFR and DPD optimization for 5G Digital Front Ends

    University essay from Lunds universitet/Matematik LTH

    Author : Gustav Olsson; [2023]
    Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

    Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

  3. 2. CLEO

    University essay from Lunds universitet/Industridesign

    Author : Nina Cherrug; [2022]
    Keywords : Arts and Architecture; Technology and Engineering;

    Abstract : For every cosmetic product a consumer buys, a new packaging (often plastic) is purchased together with it. Every year, this single-use behavior stands for 120 billion units of cosmetic packaging. For Europe alone, this is the equivalent of 5 packed Avicii Arenas. READ MORE

  4. 3. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

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

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

  5. 4. Robust post impact vehicle motion control using torque vectoring

    University essay from KTH/Fordonsdynamik

    Author : Nikhil Jain; [2019]
    Keywords : ;

    Abstract : Several statistical studies have suggested that the risk of injury is significantly higher in multiple event accidents (MEAs) than in single event crashes. Improper driving in such scenarios leads to hazardous vehicle heading angles and excessive lateral deviations from thevehicle path, resulting in severe secondary crashes. READ MORE

  6. 5. Development of a tool allowing to create and use JSON schemas so as to enhance the validation of existing projects

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Simon Charles-Elie; [2017]
    Keywords : Application programming interface; Representational state transfer; JSON schema; Resource; Route;

    Abstract : A mobile application is typically divided into two sides that communicate with each other: the front-end (i.e. what the user can see and interact with on the phone) and the back-end (the hidden ”server” side, which processes requests from the front-end). READ MORE
