Item Efficient Solution of a Toeplitz-Plus-Hankel Coefficient Matrix System of Equations(1980-05-01) Merchant, G.A.; Parks, T.W.Frequently in signal processing one is faced with situations where a large system of linear equations, with a Toeplitz or a Hankel coefficient matrix, needs to be solved. One efficient way of solving these kinds of equations is by Levinson recursion. The Levinson recursion does not require explicit storage of the Toeplitz (or Hankel) coefficient matrix and the number of multiplies required is proportional to the square of the number of unknowns.Item Magnitude Weighting and Time Segmentation for Phase-Only Reconstruction of Signals(1981-04-01) Merchant, G.A.; Parks, T.W.Phase-only reconstruction of signals and its application to blind-deconvolution were introduced recently by Oppenheim, and by Hayes, et.al. In this report, we briefly present another description of this phase-only reconstruction, propose a new magnitude weighted reconstruction and show how these ideas can be applied to the deconvolution of segmented data.
