A universal characterization of maximum-entropy covariances for multidimensional signals is presented. We show that the maximum-entropy extension of an arbitrary partial covariance of a nonstationary multidimensional signal always has what we call a banded inverse, i.e., the inverse is sparse and has the same support as the given partial covariance. We(More)
A technique for performing exact calculations it discussed. The technique uses single-modulus P arithmetic to perform calculations over the finite field of integers and the finite ring of integers. It is shown that the arithmetic operations modulo P (which obviously can be impleinented in microprocessor configurations, VLSI, and/or software) can easily be(More)
