Abstract :
The energy compaction performance of two-channel paraunitary finite impulse response (FIR) filter banks for finite-length signals is investigated. A detailed non-iterative design procedure for boundary filters which are optimal in a weighted mean square error (MSE) sense in the Fourier domain is presented. Simulation results are given for two-channel paraunitary FIR filter banks based on minimum-phase Daubechies filters and least-asymmetric Daubechies filters, respectively
