We propose a theoretical scheme to improve the resolution and precision of phase measurement with parity detection in Mach-Zehnder interferometer by using nonclassical input state which is generated applying number-conserving generalized superposition products (GSP) operation, (saa^{{\dag}}+ta^{{\dag}}a)^{m} s^2+t^2=1, on two-mode squeezed vacuum (TMSV) state. The properties proposed GSP-TMSV a...

Estimating correctly the quantum phase of a physical system is central problem in parameter estimation theory due to its wide range applications from metrology cryptography. Ideally, optimal estimator given by so-called Cramér-Rao bound, so any measurement strategy aims obtain estimations as close possible it. However, more often than not, current state-of-the-art methods estimate phases fail r...

A single-channel source separation (SCSS) algorithm is targeted to estimate the underlying unknown signals from their single-channel recorded mixture. Current SCSS methods often neglect the phase information in their parameter estimation and use the noisy phase in the signal reconstruction stage. In this paper, we investigate the impact of phase information in the parameter estimation stage of ...

Synthetic aperture radar interferometry (InSAR) is an important remote sensing technique to retrieve the terrain digital elevation model (DEM)[1][2]. Image coregistration, InSAR interferometric phase estimation (or noise filtering) and interferometric phase unwrapping[3][4][5][6] are three key processing procedures of InSAR. It is well known that the performance of interferometric phase estimat...

This letter proposes a highly accurate trajectory estimation method for outdoor mobile robots using global navigation satellite system (GNSS) time differences of carrier phase (TDCP) measurements. By GNSS TDCP, the relative 3D position can be estimated with millimeter precision. However, when phenomenon called cycle slip occurs, wherein measurement jumps and becomes discontinuous, it is impossi...
