  1. 1. Examining the Effects of AWGN Jamming on a Tactical Data Link Communication System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Noor Schroen; [2023]
    Nyckelord :Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming;

    Sammanfattning : This master thesis investigates the jamming of Tactical Data Links (TDLs). The goal is to make a model that is capable of giving an overview of a communication system under jamming conditions, offering the user a suggestion for the best coding scheme and modulation to use in any given situation.

  3. 2. A 1.8 ps Time-to-Digital Converter (TDC) Implemented in a 20 nm Field-Programmable Gate Array (FPGA) Using a Ones-Counter Encoding Scheme with Embedded Bin-Width Calibrations and Temperature Correction

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Engström Sven; [2020]
    Nyckelord :time-to-digital; time-to-digital converter; TDC; 1.8 ps; field-programmable gate array; FPGA; 20 nm; Xilinx; Kintex; UltraScale; tapped delay line; TDL; taps; carry-chain; ones-counter; bit-counter; bubbles; wave-union; embedded; temperature correction;

    Sammanfattning : This thesis investigates the use of field-programmable gate arrays (FPGAs) to implement a time-to-digital converter (TDC) with on-chip calibration and temperature correction.Using carry-chains on the Xilinx Kintex UltraScale architecture to create a tapped delay line (TDL) has previously been proven to give good time resolution.

  4. 3. Assessing blockchain technology for Transport Data Logger

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

    Författare :Björn Johansson; [2018]
    Nyckelord :blockchain; transport data logger; hyperledger; hyperledger fabric; byzantine fault tolerance; bft; supply chain; transport chain; permissioned; permissionless; documental truth; historical truth; immutability; security; log data; Technology and Engineering;

    Sammanfattning : A proof of concept permissioned blockchain system that holds data from the Transport Data Logger, TDL, was developed. Transport chain actors who hand off TDL-equipped goods between one another use the TDL app to upload a digital handoff containing their identities and log data from and signed by the TDL to a Hyperledger Fabric blockchain network.

  5. 4. Design Philosophy for User Friendly Parameter Handler

    Master-uppsats, Akademin för innovation, design och teknik

    Författare :Angie Angarita Soto; [2012]
    Nyckelord :Drive Unit Control; Engine Unit Control; ASAM; online calibration and measurement; model based development;

    Sammanfattning : DCU2 (Drive Control Unit 2) is an important control system used in applications for train systems that are configured by a set of parameters. Traditionally, parameterization is conducted by using an excel workbook during the software development. The parameters are set up and further export the parameters to the compilation step. LÄS MER

  7. 5. Self-Organized TDMA protocol for Tactical Data Links

    Master-uppsats, Kommunikationssystem

    Författare :Wichai Pawgasame; Wuttisak Sa-Ad; [2011]
    Nyckelord :Self-organized TDMA; Tactical Data Links;

    Sammanfattning : A Tactical Data Link (TDL) system has been deployed in many military missions as a winning strategy. The performance of a TDL system is governed by the MAC protocol. The MAC protocol that is able to provide more flexibility and high quality of services is more desirable. LÄS MER
