A log spectral approach to bidirectional deconvolution

Jon Claerbout, Qiang Fu, and Yi Shen


The blind-deconvolution problem for non-minimum-phase-source was established in the time domain. This is a Fourier domain formulation. Changing variables from $ A(Z)B(1/Z)$ to $ U(Z)=\ln(A(Z)B(1/Z))$ leads to a different kind of whiteness -- the output being orthogonal to its shifted soft clip.
