A digital phase‐based on‐fly offset compensation method for decision feedback equalisers
IET Circuits, Devices and Systems, 2021 A low‐complexity method to reduce the offset voltage of dynamic comparators employed as samplers in decision feedback equalisers (DFE) is introduced. The authors propose the phase‐domain offset reduction technique (PORT), which leverages an all‐digital ...

A highly accurate DFT-based parameter estimator for complex exponentials
Journal of Telecommunications and Information Technology, 2006 A highly accurate DFT-based complex exponential parameter estimation algorithm is presented in this paper. It will be shown that for large number of samples and high signal to noise ratio (SNR), the phase estimation error variance performance is only 0 ...

Phase Estimation of Single Tones Next to Modulated Signals in the Medium Frequency R-Mode System
IEEE Access, 2022 Position, navigation, and timing information are critical to today’s infrastructures; as a result, the possibility of estimating ranges is being explored in more and more radio systems. One way to achieve this is to extend the modulation with time-

Generation of eigenstates using the phase-estimation algorithm [PDF]
, 2001 The phase estimation algorithm is so named because it allows the estimation of the eigenvalues associated with an operator. However it has been proposed that the algorithm can also be used to generate eigenstates.

Phase-based ultrasonic deformation estimation [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2008 Deformation estimation is the foundation of emerging techniques for imaging the mechanical properties of soft tissues. We present theoretical analysis and experimental results from an investigation of phase-based ultrasonic deformation estimators. Numerous phase-based algorithm variants were tested quantitatively on simulated RF data from uniform ...

Iterative phase estimation [PDF]
Journal of Physics A: Mathematical and Theoretical, 2009 We give an iterative algorithm for phase estimation of a parameter theta, which is within a logarithmic factor of the Heisenberg limit. Unlike other methods, we do not need any entanglement or an extra rotation gate which can perform arbitrary rotations with almost perfect accuracy: only a single copy of the unitary channel and basic measurements are ...

Positioning in a Multipath Channel Using OFDM Signals With Carrier Phase Tracking
IEEE Access, 2020 In developing a high accuracy terrestrial radio navigation system, as a complement to a global navigation satellite system (GNSS), it is recognized that the performance of time delay estimation is proportional to, and thereby limited by, the signal ...
