Frequency estimation by frequency jumps
npj Quantum InformationThe frequency of a quantum harmonic oscillator cannot be precisely determined through static measurement strategies on a prepared state. Therefore, dynamical procedures must be employed, involving measurements taken after the system has evolved and ...

Blind Frequency Estimation and Symbol Recovery for the Analytically Solvable Chaotic System [PDF]
Entropy, 2019 The analytically solvable chaotic system (ASCS) is a promising chaotic system in chaos communication and radar fields. In this paper, we propose a maximum likelihood estimator (MLE) to estimate the frequency of ASCS, then a difference-integral (DI ...

A high‐precision frequency estimation algorithm based on multi‐segment signal fusion
IET Radar, Sonar & Navigation, 2023 As the current multi‐segment signal fusion algorithms cannot meet the requirement of high‐precision frequency estimation at different signal‐to‐noise ratios (SNRs), an adaptive fusion algorithm is proposed in this paper.
