Reconstruction of signals from phase - Efficient algorithms, segmentation, and generalizations

In this paper, several new formulations of the phase-only reconstruction problem are developed which lead to new, efficient algorithms for signal reconstruction. A procedure is described for approximately reconsructing a long duration signal from short segments. Phase-only blind deconvolution for linear phase filters relies on mirror image symmetry in the filter transfer function H(z). This deconvolution result is generalized to include several other types of symmetries for H(z).
