The Role of Linear Semi{innnite Programming in Signal{adapted Qmf Bank Design

Abstract

We consider the problem of designing a perfect{reconstruction, FIR, quadrature{mirror lter (QMF) bank (H; G) adapted to input signal statistics, with coding gain as the adaptation criterion. Maximization of the coding gain has so far been viewed as a diicult nonlinear constrained optimization problem. In this paper, it is shown that in fact the coding gain… (More)
