  1. 11. Effects of Design Space Discretization on Constraint Based Design Space Exploration

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Ludwig Karlsson; [2023]
    Nyckelord :Constraint programming; Design space exploration; Discretization; Multiresolutional analysis; Villkorsprogrammering; Designrymdsutforskning; Diskretisering; Multiupplösningsanalys;

    Sammanfattning : Design Space Exploration (DSE) is the exploration of a space of possible designs with the goal of finding some optimal design according to some constraints and criteria. Within embedded systems design, automated DSE in particular can allow the system designer to efficiently find good solutions in highly complex design spaces. LÄS MER

  3. 12. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Nyckelord :5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Sammanfattning : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. LÄS MER

  4. 13. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Daniel Spegel-Lexne; [2022]
    Nyckelord :beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

    Sammanfattning : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. LÄS MER

  5. 14. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

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

    Författare :Bharat Maheshwari; Yewen Zhou; [2022]
    Nyckelord :error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Sammanfattning : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. LÄS MER

  7. 15. Predictable Multiprocessor Platform for Safety- Critical Real- Time Systems

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

    Författare :Páll Axel Sigurðsson; [2021]
    Nyckelord :Composability; FPGA; Multicore processing; Predictability; Real- time systems; System on chip; FPGA; Förutsägbarhet; Komposibilitet; Mångkärnig bearbetning; Realtidssystem; System på chip;

    Sammanfattning : Multicore systems excel at providing concurrent execution of applications, giving true parallelism where all cores can execute sequences of machine instructions at the same time. However, multicore systems come with their own sets of problems, most notably when cores in a system (or core tiles) share hardware components such as memory modules or Input/Output (IO) peripherals.
