Quantum Limits of Thermometry [PDF]
, 2010 The precision of typical thermometers consisting of $N$ particles is shot noise limited, improving as $\sim1/\sqrt{N}$. For high precision thermometry and thermometric standards this presents an important theoretical noise floor.

CAPE: combinatorial absolute phase estimation [PDF]
Journal of the Optical Society of America A, 2009 An absolute phase estimation algorithm for interferometric applications is introduced. The approach is Bayesian. Besides coping with the 2pi-periodic sinusoidal nonlinearity in the observations, the proposed methodology assumes a first-order Markov random field prior and a maximum a posteriori probability (MAP) viewpoint. For computing the MAP solution,

Precision bounds for noisy nonlinear quantum metrology [PDF]
, 2014 We derive the ultimate bounds on the performance of nonlinear measurement schemes in the presence of noise. In particular, we investigate the precision of the second-order estimation scheme in the presence of the two most detrimental types of noise ...

Efficient knowledge-aided target relocation algorithm for airborne radar
The Journal of Engineering, 2019 This letter addresses the problem of target relocation in wide-area ground moving target indication system. The antenna pattern information is exploited as prior knowledge to enhance the performance of airborne radar. Firstly, the ideal target relocation

Testing of quantum phase in matter wave optics
, 1999 Various phase concepts may be treated as special cases of the maximum likelihood estimation. For example the discrete Fourier estimation that actually coincides with the operational phase of Noh, Fouge`res and Mandel is obtained for continuous Gaussian ...

Pilot-aided carrier synchronization using an approximate DCT-based phase noise model [PDF]
, 2007 This contribution deals with phase noise estimation from pilot symbols. The phase noise process is approximated by an expansion of DCT basis functions containing only a few terms.
