A new concept for reconstructing a class of signals is introduced. The signal under construction is modeled as a product of terms. Different approaches can be used to estimate these terms separately. Seismic signal processing is used as an illustrative example, i.e. a simulated seismic reflected wave is reconstructed in a noisy environment. This wave is modeled as an attenuated and delayed version of a known incident wave. The time delay is estimated using cross correlation, and the maximum-entropy method (MEM) is used to estimate the attenuation factor. It is also reformulated as an efficient MEM image reconstruction algorithm. The efficient MEM algorithm is shown to yield better results than conventional methods
