Abstract
In this paper we present three new algorithms for sparse multichannel
blind deconvolution. The first algorithm is based on a cascade of a
forward and a backward prediction error filter. The second consists in
an alternating minimization algorithm for estimating both the
reflectivity series and the seismic wavelet. The last one is a
regularized version of the so called Euclid deconvolution, solved by the
well known fast iterative shrinkage-thresholding algorithm (FISTA).
Simulation results illustrate that the three algorithms presents some
quite interesting results in both synthetic and real data.
