Optomechanical parameter estimation
New Journal of Physics, 2013 We propose a statistical framework for the problem of parameter estimation from a noisy optomechanical system. The Cramér–Rao lower bound on the estimation errors in the long-time limit is derived and compared with the errors of radiometer and ...

The hybrid Cramér-Rao lower bound for simultaneous self-localization and room geometry estimation
EURASIP Journal on Advances in Signal Processing, 2021 This paper addresses the problem of tracking a moving source, e.g., a robot, equipped with both receivers and a source, that is tracking its own location and simultaneously estimating the locations of multiple plane reflectors.

Frequency estimator by combination of phase difference method and interpolation algorithm
Journal of Algorithms & Computational Technology, 2019 In the traditional time-shifting based phase difference method, considerable errors may be introduced by wrapped phase problem as long as translation coefficient tends to one even in a small-scale turbulence noise.

On stability of generalized (affine) phase retrieval in the complex case
Journal of Inequalities and Applications, 2019 In this paper, we discuss the stability of generalized phase retrieval and generalized affine phase retrieval in the complex case. By the realification method, we obtain the bi-Lipschitz property in the absence of noise case and Cramer–Rao lower bound ...

Valid lower bound for all estimators in quantum parameter estimation
New Journal of Physics, 2016 The widely used quantum Cramér–Rao bound (QCRB) sets a lower bound for the mean square error of unbiased estimators in quantum parameter estimation, however, in general QCRB is only tight in the asymptotical limit.
