Excerpt from Deconvolution of Acoustic Emission and Other Causal Time Series, Vol. 96: May-June 1991This is usually done by replacing an a priori range estimate with more accurate a posteriori range data where available. It can be done from the domain by convolving an a priori domain esti mate with the kernel to give the a priori range esti mate. Since the root projection of an a priori range estimate in this case is equal to itself, an equivalent method here is to subtract the a prion' range esti mate from the a posteriori range data, where avail able, and fill out the rest of the range with zeroes to produce a reduced problem with a zero a priori estimate. The a priori domain estimate can then be added back on to the inversion estimate from the reduced problem to give an upgraded inversion es timate. This latter approach can also be directly applied to introduce a priori information into the lanczos/svd method.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
