  1. 1. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels

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

    Author : Prasetyo Putranto; [2023]
    Keywords : Channel aging; Pilot spacing; Rayleigh; Rician; Spectral efficiency; Uncrewed aerial vehicles; Kanalåldring; Pilotavstånd; Rayleigh; Rician; Spectral effektivitet; Obemannade flygfordon;

    Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE

  3. 2. Channel Estimation and Power Control Algorithms in the Presence of Channel Aging

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

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

    Abstract : 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. READ MORE

  6. 5. The Role of Social Capital on Foreign Direct Investments: Evidence from Cross-Country Regressions

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Thilda Horvath; [2022]
    Keywords : FDI; Foreign direct investments; Social capital; Cross-country regression; Business and Economics;

    Abstract : Since the world witnessed a surge of cross-border investments as a source of economic activity, the relevance, determinants and nature of the phenomenon we call Foreign Direct Investments (FDI) has been studied extensively. The amount of empirical studies is not only extensive but also controversial, as the authors frequently reach contradictory conclusions in their search for determinants, relying only on the assumptive realities of economic theory.
