Abstract
The optimization of two-band paraunitary finite impulse response (FIR) filter banks for finite-length signals is considered. Boundary filters which are optimal in a weighted mean square error (MSE) sense in the Fourier domain and the associated stationary filters are optimized simultaneously. Simulation results reveal that the maximally flat Daubechies filters are nearly optimal with respect to energy compaction performance
