Puduru Viswanadha Reddy, Anamitra Makur · 2004
In this work, the problem of design of M channel biorthogonal FIR perfect reconstruction filter banks (FIRPRFB) is addressed using spectral theory of matrix polynomials. The present characterization covers a broader class of filter banks. Some insightful results on reconstruction delay and length of synthesis filters are presented, both of these parameters can be varied in the present characterization. Simulation results are presented for 2,3,4 channel designs.
