A multichannel approach to long-period multiple prediction and attenuation

A method is presented for the prediction and attenuation of long-period wat er-layer multiples based on an adaptive multichannel lattice algorithm. The multichannel approach can be viewed as a generalization of two-dimensional linear prediction. The multichannel linear least-squares prediction proble m is reviewed briefly and the performance and limitations of the algorithm are demonstrated on two different marine data sets with different propertie s of the simple sind peg-leg multiple system. The algorithm works well even on problematic data sets and is very easy to apply.
