A mean-square error lower bound for the discrete-time nonlinear filtering problem is derived
based on the van Trees (1968)(posterior) version of the Cramer-Rao inequality. This lower …

A detector has been developed which can reliably detect right whale calls and distinguish
them from those of other marine mammals and industrial noise. Detection is a two stage …

Chirp signals arise in many applications of signal processing. In this paper, we address the
problem of detection of chirp signals that are encountered in a bistatic radar which we are …

We study and compare four algorithms for adaptive retrieval of slowly time-varying multiple
cisoids in noise: the adaptive notch filter, the multiple frequency tracker, the adaptive …

The online detection of a very long and weak chirp signal is studied. The signal has an
extremely slowly decreasing frequency, and is corrupted by white Gaussian noise and …

Adaptive notch filters have been the focus of intense research for more than three decades.
Low computational requirements and good performance make them attractive for tracking …

Daily mean near‐surface air temperature series from seven European locations were
processed in order to obtain reliable estimates of instantaneous phases of the annual cycle …

In this Letter, we report on sub-millisecond response time mid-infrared dual-comb
spectroscopy using a balanced asymmetric (dispersive) dual-comb setup with a matched …

The problem of adaptive parameter estimation for a single nonstationary noisy cisoid, where
the sinusoidal frequency evolves according to Gaussian random walks, is studied. The lower …

A simple and robust non-linear filter algorithm has been proposed in this study for estimating
the frequency of a time-varying sinusoidal signal under high noise conditions. The real …
