  1. 1. 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

  3. 2. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
    Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Abstract : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. READ MORE

  4. 3. Machine Learning-based MIMO Indoor Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Qiyi Chen; [2023]
    Keywords : Technology and Engineering;

    Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Eneas Hållsten; [2022]
    Keywords : Technology and Engineering;

    Abstract : Wireless power transfer is emerging into everyday life. The idea is to create a more convenient way of charging, or at least powering, devices. READ MORE

  6. 5. Investigation on 5G Techniques for a College Scenario

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Xiaohan Wang; [2022]
    Keywords : Technology and Engineering;

    Abstract : With the development of telecommunication technology, the mobile networks are being updated. 5G is the fifth generation mobile communication, which can provide a higher data rate, lower latency, more connections, higher security insurance, and more flexible business deployment capabilities than 4G.
