An algorithm for maximum - likelihood signal estimation was devised, being based on a complicated model of the multichannel seismic record. It is supplied with estimates of the parameters needed to function. Optimum weighted stacking (OWS) may be considered to be a particular case of the algorithm. In this paper, the advantages of OWS over conventional unweighted stacking are demonstrated, the causes of low effectiveness of OWS algorithms based on simplified versions of the model used are explained and the effectiveness of our approach is demonstrated with field data.
