  1. 1. LEO Satellite Connectivity for flying vehicles

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

    Författare :Jinxuan Chen; [2023]
    Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  3. 2. Trilingual spoken word recognition : Interlingual competition from one or two non-target languages in a sentence context

    Magister-uppsats, Stockholms universitet/Centrum för tvåspråkighetsforskning

    Författare :Yulia Kashevarova; [2023]
    Nyckelord :trilingual speech processing; cross-linguistic competition; sentence context; BLINCS; BIA ;

    Sammanfattning : Persistent non-target language co-activation in spoken and visual language comprehension has been found both at the word-level and at the level of a sentence, although in the latter case, sentence bias has been observed to modulate the co-activation which can create lexical competition. In the case of trilingual speakers, both non-target languages may potentially compete with the third language (L3). LÄS MER

  4. 3. The Effect of Noise Levels on the Performance of Shor’s Algorithm

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

    Författare :Niklas Höstedt; Tobias Ljunggren; [2023]
    Nyckelord :Bachelor’s thesis; Quantum Computing; Shor’s algorithm; Noise; Cryptography; Qiskit; Kandidatexamensarbete; Kvantdatorer; Shors algorithm; Brus; Kryptografi; Qiskit;

    Sammanfattning : Advanced enough quantum computers promise to revolutionise fields such as cryptography, drug discovery and simulations of complex systems. Quantum computers are built on qubits which are fragile and susceptible to error-inducing interference, which is called noise. LÄS MER

  5. 4. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

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

    Författare :Yan Bixing; [2023]
    Nyckelord :Fading channel; auto-regressive model; power allocation; uncrewed aerial vehicle networks; Fading kanal; auto-regressiv modell; krafttilldelning; obemannade flygfordonsnätverk;

    Sammanfattning : Power allocation algorithms that determine how much power should be allocated to pilot and data symbols play an important role in addressing the trade-off between accurate channel estimation and high high spectral efficiency for data symbols in the presence of time-varying fading channels. Dealing with this trade-off is highly non-trivial when the channel changes or ages rapidly in time. LÄS MER

  7. 5. Impact of interfering rouge access points on modulationand coding in IoT network

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Amgad Shaher Saif; [2023]
    Nyckelord :Rogue access point; internet of things; modulation and coding scheme; round trip time; radio frequency interference; network latency; network security.; Obehörig åtkomstpunkt; sakernas internet; modulation och kodningsschema; round trip time; radiofrekvensinterferens; nätverkslatens; nätverkssäkerhet.;

    Sammanfattning : This Bachelor thesis presents an in-depth investigation into the effects of RogueAccess Point interference within Internet of Things networks. The study focuses onthe impact of rogue APs on the modulation and coding scheme indices, round triptime, and overall network performance. LÄS MER
