Abstract
In this paper, we present a numerical design method for two-dimensiona l (2-D) FIR linear-phase (LP) quincunx filter banks (QFB) with equirip ple magnitude response and perfect reconstruction (PR). The necessary conditions for the filter length of analysis filters are derived. A du al affine scaling variant (DASV) of Karmarkar's algorithm is employed to minimize the peak ripples of analysis filters and an approximation scheme is introduced to satisfy the PR constraint for the 2-D filter b anks (FB). The simulation examples are included to show the effectiven ess of this proposed design technique.
