Estimation of Chirp Signals in Gaussian Noise by Kalman Filtering
"... Abstract — the paper addresses the problem of estimating the chirp signals embedded in Gaussian noise. The proposed method is based on a model of the signal phase as a polynomial. This approach offers the opportunity to represent these signals by an adequate state space model and to apply standard K ..."

, 1998
"... We use the principles of maximum likelihood estimation to construct a method for decomposing signals into a weighted sum of chirped Gabor functions. This method provides a sparse representation of the signal similar to basis and matching pursuit methods. However since the parameters of the chirps ar ..."

APPLICATION OF THE FANCHIRP TRANSFORM TO HYBRID SINUSOIDAL+NOISE MODELING OF POLYPHONIC AUDIO
"... Reliable classification of spectral peaks as tonal and noiserelated is an important stage of hybrid sinusoidal+noise modeling. Spectral peaks of higher harmonics are often missed due to their wide frequency spread resulting from pitch variation. Recently introduced fanchirp transform allows for com ..."

Bayesian Spectrum and Chirp Analysis
, 1996
"... : We seek optimal methods of estimating power spectrum and chirp (frequency change) rate for the case that one has incomplete noisy data on values y(t) of a time series. The Schuster periodogram turns out to be a "sufficient statistic" for the spectrum, a generalization playing the same ro ..."
