  1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Improvement of the robustness and performance of time of arrival algorithms

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Kristian Huotila; [2021]
    Nyckelord :;

    Sammanfattning : 5G offers several new improvements compared to its predecessors, such as higher speeds, lower latency and larger capacity. In order to ensure this, time of arrival algorithms are used in the Radio Access Networks for several purposes. Some of them are 3D positioning of User Equipment and synchronization. LÄS MER

  4. 3. Flying is Dangerous - That is why it is so safe : Miscommunication in aviation

    Kandidat-uppsats, Karlstads universitet/Fakulteten för humaniora och samhällsvetenskap (from 2013)

    Författare :Christer Thörnqvist; [2020]
    Nyckelord :Aviation; communication; two-way radio; Air Traffic Control – ATC; pilot; Crew Resource Management - CRM; Controller Pilot Data-Link Communications – CPDLC; Runway Incursion;

    Sammanfattning : In this essay one has been investigating some of the reasons why aviation incidents take place and also examine what strategies there are to minimize the risks - primarily regarding miscommunication which often seems to be a contributing element or a direct cause in aviation mishaps. The aim of this study is to highlight and raise awareness about this field of study from a communicative point of view. LÄS MER
