Design of Biorthogonal FIR Linear Phase Filter Banks with Structurally Perfect Reconstruction

摘要

In the design of two channel perfect reconstruction filter banks, most of the conventional methods optimize the frequency response of each filter to meet the perfect recon- struction condition. However, quantization of the filter co- efficient results in some errors in the frequency response, so it is not guaranteed that the perfect reconstruction con- dition is still satisfied. In this paper, we present a new method for designing biorthogonal FIR linear phase filter banks with structurally perfect reconstruction.
