B029 Robust Wavelet Estimation and Blind Deconvolution of Noisy Surface Seismics M.A. van der Baan* (University of Leeds) & D.T. Pham (LMC-IMAG) SUMMARY Robust blind deconvolution is a challenging problem - in particular if the bandwidth of the wavelet is quite narrow (say around 2 octaves). The principal problem is to estimate the phase of the wavelet with sufficient accuracy. The mutual information rate is a general-purpose criterion to measure whiteness using statistics of all orders. We derive a modification of this criterion that measures the phase of the wavelet within its passband yet remains stable in the presence of
