Distributed Target Detection with Coherent Fusion in Tracking Based on Phase Prediction

Remote Sensing
In distributed radar, a coherent system often gains attention for its higher detection potential in contrast to its non-coherent counterpart. However, even for a distributed coherent radar, it is difficult to coherently accumulate local observations in ...

Poboljšanje sinhronizacije signala u softverskom GPS prijemniku / Improvement of signal synchronization in GPS software receiver / Улучшение синхронизации сигнала в программируемом GPS приемнике

Vojnotehnički Glasnik, 2015
In GPS receivers, navigation bit allocation is performed throughout the process of signal tracking and detection. In the process of signal tracking, the locally generated signal must be synchronized with the received signal. The Costas phase-locked loop (

Agnostic Phase Estimation

Physical Review Letters
The goal of quantum metrology is to improve measurements' sensitivities by harnessing quantum resources. Metrologists often aim to maximize the quantum Fisher information, which bounds the measurement setup's sensitivity. In studies of fundamental limits on metrology, a paradigmatic setup features a qubit (spin-half system) subject to an unknown ...

Demystifying DFT-Based Harmonic Phase Estimation, Transformation, and Synthesis

Signals
Many natural signals exhibit quasi-periodic behaviors and are conveniently modeled as combinations of several harmonic sinusoids whose relative frequencies, magnitudes, and phases vary with time.

Applicability of the six-phase method for auricular age estimation in an Indian population: A CT-based study

, 2023
Age estimation plays a crucial role in human identification. Amongst numerous age markers located throughout the skeletal framework, the auricular surface of the ilium presents as a resilient structure, with different methods for auricular age estimation

Non-Data-Aided Cycle Slip Self-Correcting Carrier Phase Estimation for QPSK Modulation Format of Coherent Wireless Optical Communication System

IEEE Access, 2019
In this study, we propose a non-data-aided algorithm of the cycle slip self-correcting carrier phase estimation (CSSC-CPE) which mitigates the cycle slips caused by blind CPE in the coherent wireless optical communication (WOC) system.
