A New Strategy of Quantum-State Estimation for Achieving the Cramer-Rao Bound [PDF]
, 2002 We experimentally analyzed the statistical errors in quantum-state estimation and examined whether their lower bound, which is derived from the Cramer-Rao inequality, can be truly attained or not.

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 ...

Cramér–Rao lower bound for ATSC signal‐based passive radar systems
Electronics Letters, 2019 In multistatic passive radar systems, the Cramér–Rao lower bound (CRLB) can be used to select the optimal illuminator of opportunity so that it provides the best estimation accuracy for target parameters.

Cramér-Rao Lower Bound of Target Localization Method Based on TOA Measurements
Xibei Gongye Daxue Xuebao, 2019 The Cramér-Rao bound of target localization method based on time-of-arrival measurements is analyzed. For the localization error analysis, the CRLB is derived under the assumptions that the measurement errors are independent and characterized by zero ...

Lower bounds on the estimation performance in low complexity quantize-and-forward cooperative systems [PDF]
, 2015 Cooperative communication can effectively mitigate the effects of multipath propagation fading by using relay channels to provide spatial diversity. A relaying scheme suitable for half-duplex devices is the quantize-and-forward (QF) protocol, in which ...

The modified cramer-rao bound for channel estimation in quantize-and-forward cooperative systems [PDF]
, 2013 The quantize-and-forward (QF) cooperative protocol can effectively be used to combat fading in systems using half-duplex relay terminals. While the outage behavior of the QF protocol has been extensively investigated, few research has been performed on ...

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 ...

On the Cramer-Rao bound for carrier frequency estimation in the presence of phase noise [PDF]
, 2007 We consider the carrier frequency offset estimation in a digital burst-mode satellite transmission affected by phase noise. The corresponding Cramer-Rao lower bound is analyzed for linear modulations under a Wiener phase noise model and in the hypothesis
