  4. 3. 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
