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. Technologies and Evaluation Metrics for On-Board Over the Air Control

4. 3. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

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

   Author : Xi Chen; [2015]
   Keywords : V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

   Abstract : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). READ MORE

5. 4. Comparison and Evaluation of Doppler Spread Estimation Algorithms in WCDMA

   University essay from KTH/Kommunikationsteori

   Author : Hui Wen; [2014]
   Keywords : ;

   Abstract : In a WCDMA transmission systems, the properties of the radio transmissionchannels can be strongly aected by the movement of User Equipment (UE) orthe surrounding objects. The estimation of Doppler spread is therefore of greatimportance since it is closely related to the mobile speed, as it can also be usedto characterize the fast fading in the radio channel.

6. 5. Performance and Complexity Comparison of Doppler Spread Estimation for WCDMA Systems

   University essay from KTH/Kommunikationsteori

   Author : Ziqi Peng; [2014]
   Keywords : Doppler spread estimation; WCDMA uplink systems; Rayleigh fading model; Rician fading model; computational complexity.;

   Abstract : In cellular communication systems, the estimation of Doppler spread has a wide range of applications such as handoff, channel assignment scheme, adaptivetransmission, power control, etc. A great quantity of Doppler spread estimation algorithms have been proposed in the literature.
