Theory and design of optimum FIR compaction filters
Energy compaction filters have attracted considerable attention due in part, to the fact that they are the building blocks of optimal orthonormal (paraunitary) filter banks. In this paper we introduce some new design techniques for optimum M-channel FIR compaction filters for a given input power spectrum. Some properties of the optimum FIR compaction filters and the corresponding maximum compac...
متن کاملTHEORY AND DESIGN OF OPTIMUM FIR COMPACTION FILTERSz
The problem of optimum FIR energy compaction lter design for a given number of channels M and a lter order N is considered. The special cases where N < M and N = 1 have analytical solutions that involve eigenvector decomposition of the autocorrelation matrix and the power spectrum matrix respectively. In this paper, we deal with the more diicult case of M < N < 1. For the two-channel case and f...

Energy compaction has proven to be an essential concept in signal-adapted data compression. In particular, optimization of orthonormal subband coders for a given power spectrum directly leads to optimal energy compaction lters. In this paper, we consider some new design methods and properties of optimal FIR energy compaction lters. In particular , we propose a very eecient method called the win...

متن کاملcient Design Methods of Optimal FIR Compaction Filters forM - channel FIR
We propose algorithms for the design of FIR com-paction lters, which nd applications in FIR subband coders. The techniques produce compaction gains very close to that of optimal compaction lters, for any xed lter order and input autocorrelation. The main theme of the paper is the design of multistage FIR com-paction lters based on an iterated linear programming approach. The theory behind this ...
