Iterative deblending of simultaneous-source seismic data using seislet-domain shaping regularization |

where is a block operator that takes the form , and and correspond to the shaping operators for and , respectively. Using equation 7 and performing appropriate iterations, we aim to get an estimate of unblended seismic data.

To test the convergence performance and accuracy of iteration 7, we use the following measure (Hennenfent and Herrmann, 2006):

where stands for signal-to-noise ratio of th source after th iteration, denotes the estimated model of th source after iterations, denotes the true model for th source and denotes the squared norm of a function.
