Abstract

Abstract

Signal-adapted institute of filter banks are an important subject in the theory and applications of the multirate filter banks.Since the frequency responses match the statistics of the underlying signals very well， these filter banks achieve the larger subband coding gains. This paper investigates the design of two-band signal-adapted biorthogonal linear phase filter banks and gives the design algorithm, in particular, the method to determine the initial points (initial filter banks) with the optimal IIR biorthogonal filter banks that is easy to be obtained. The result of emulation indicates that the subband coding gains of the resulted filter banks are excess those of the optimal IIR paraunitary filter banks much, and comparing with the existing results the subband coding gains are markedly improved.
