Distributed Frequency Offsets Estimation [PDF]
2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018 In this paper, we provide a distributed frequency offset estimation algorithm based on a variant of belief propagation (BP). Each agent in the network pre-compensates its carrier frequency individually so that there is no frequency offset from the desired carrier frequency between each pair of transceiver.

Frequency-Locked Loop Based on a Repetitive Controller for Grid Synchronization Systems
IEEE Access, 2020 The frequency-locked loop based on a second-order generalized integrator has been widely used in grid synchronization systems but featuring unfavorable harmonics filtering performance. To solve this issue, a frequency-locked loop based on multiple second-

Availability and category-frequency estimation [PDF]
Memory & Cognition, 1991 Individuals judged how often examples of taxonomic categories had occurred in a study list. An availability hypothesis was tested--that frequency estimates are based on the retrieval of instances. Cued (by category names) recall of the examples served as an index of availability.

An Improved Performance Frequency Estimation Algorithm for Passive Wireless SAW Resonant Sensors
Sensors, 2014 Passive wireless surface acoustic wave (SAW) resonant sensors are suitable for applications in harsh environments. The traditional SAW resonant sensor system requires, however, Fourier transformation (FT) which has a resolution restriction and decreases ...

A Novel Monopulse Angle Estimation Method for Wideband LFM Radars
Sensors, 2016 Traditional monopulse angle estimations are mainly based on phase comparison and amplitude comparison methods, which are commonly adopted in narrowband radars. In modern radar systems, wideband radars are becoming more and more important, while the angle

Estimating a frequency unseen: an application to ornithology [PDF]
Statistica Neerlandica, 2005 The second author is involved in a capture–mark–recapture study of some wader species. Part of his program deals with resight observations. On a particular day he visually inspects a fairly stable population to identify the ringed birds by reading their ring‐number. Some ringed birds will be missed, so observations are repeated on other days. The issue
