  1. 1. Classification of Radar Emitters using Semi-Supervised Contrastive Learning

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

    Author : Tim Jonsson; [2023]
    Keywords : ;

    Abstract : Radar is a commonly used radio equipment in military and civilian settings for discovering and locating foreign objects. In a military context, pilots being discovered by radar could have fatal consequences. READ MORE

  3. 2. 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.

  6. 5. Performance Analysis Of Massive MIMO With Port Reduction

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

    Author : Tingrui Zhang; [2022]
    Keywords : 5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Abstract : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.
