On the zeros of the spectrogram of white noise
Rémi Bardenet, Julien Flamant, Pierre Chainais
In a recent paper, Flandrin [2015] has proposed filtering based on the zeros of a spectrogram, using the short-time Fourier transform and a Gaussian window. His results are based o…
Spectral analysis of stationary random bivariate signals
Julien Flamant, Nicolas Le Bihan, Pierre Chainais
A novel approach towards the spectral analysis of stationary random bivariate signals is proposed. Using the Quaternion Fourier Transform, we introduce a quaternion-valued spectral…
Time-frequency analysis of bivariate signals
Julien Flamant, Nicolas Le Bihan, Pierre Chainais
Many phenomena are described by bivariate signals or bidimensional vectors in applications ranging from radar to EEG, optics and oceanography. The time-frequency analysis of bivari…
