SUMMARY: (...): H. Omer (LATP): Estimation of frequency modulations on wide
 band signals\\\, applications to audio signal analysis
DESCRIPTION:: Estimation of frequency modulations on wideband signals\\\, a
 pplications to audio signal analysis\n\nBy Harold Omer\\\, LATP.\n\nAbstra
 ct:\nThe problem of joint estimation of power spectrum and modulation from
  realizations of frequency modulated stationary wideband signals is consid
 ered.\nThe study is motivated by some specific signal classes from which d
 epartures to stationarity can carry relevant information and has to be est
 imated.\nThe estimation procedure is based upon explicit modeling of the s
 ignal as a wideband stationary Gaussian process\\\, transformed by time-de
 pendent\\\, smooth frequency modulation. Under such assumptions\\\, an app
 roximate expression for the second order statistics of the transformed sig
 nal's Gabor transform is obtained\\\, which leads to an approximate maximu
 m likelihood estimation procedure.
