Minimized roundoff noise and pole sensitivity subject to L2-Scaling constraints for IIR filters
This paper investigates the minimization problem of weighted roundoff noise and pole sensitivity subject to l2-scaling constraints for state-space digital filters. A new measure for evaluating roundoff noise and pole sensitivity is proposed, and an efficient technique for minimizing this measure is developed. It is shown that the problem can be converted into an unconstrained optimization probl...
متن کاملOn causal linear phase IIR digital filters
Abstruct-This paper addresses the issue of the existence of causal linear phase IIR digital filters. The conditions for their existence are derived, and a set of examples satisfying these conditions is given. Specifically, the sequences must be integer samples of a continuous-time function, band-limited to ( n, n), which is symmetric and has zero crossings at the negative integers. Also, the po...
متن کاملMinimizing Nonconvex Quadratic Functions Subject to Bound Constraints
We present an active-set algorithm for finding a local minimizer to a nonconvex bound-constrained quadratic problem. Our algorithm extends the ideas developed by Dostál and Schöberl that is based on the linear conjugate gradient algorithm for (approximately) solving a linear system with a positive-definite coefficient matrix. This is achieved by making two key changes. First, we perform a line ...
متن کاملCompact Linearization for Binary Quadratic Problems subject to Assignment Constraints
We prove new necessary and sufficient conditions to carry out a compact linearization approach for a general class of binary quadratic problems subject to assignment constraints as it has been proposed by Liberti in 2007. The new conditions resolve inconsistencies that can occur when the original method is used. We also present a mixed-integer linear program to compute a minimally-sized lineari...
متن کاملA rank preserving flow algorithm for quadratic optimization problems subject to quadratic equality constraints
This paper concerns quadratic programming problems subject to quadratic equality constraints such as arise in broadband antenna array signal processing and elsewhere. At first, such a problem is converted into a semidefinite programming problem with a rank constraint. Then, a rank preserving flow is used to accommodate the rank constraint. The associated gradient formulas are carefully develope...
