  • Blind estimation of long impulse response and non-minimum phase wavelets application to seismic data 
    Benayad Nsiri; Thierry Chonavel; Jean-Marc Boucher (2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings.(ICASSP'03)., 2003-04-06)
    In seismic deconvolution, blind approches must be considered in situations where the reflectivity sequence, the source wavelet signal and the noise power level are unknown. In the presence of long, non minimum-phase, ...
  • SEM blind identification of ARMA models application to seismic data 
    Benayad Nsiri; Thierry Chonavel; Jean-Marc Boucher (2004 12th European Signal Processing Conference, 2004-09-06)
    In this paper, we address blind identification of an ARMA model convolved with an impulse sequence via Maximum Likelihood (ML) approach. A Stochastic Expectation Maximization (SEM) implementation of the criterion is ...
