Energy compaction performance of paraunitary FIR filter banks for finite-length signals
نویسنده
چکیده
The energy compaction performance of two-channel paraunitary finite impulse response (FIR) filter banks for finitelength 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 twochannel paraunitary FIR filter banks based on minimumphase Daubechies filters and least-asymmetric Daubechies filters, respectively.

Theory of Rate { Distortion { Optimal , Constrained Filter Banks
We design lter banks that are best matched to input signal statistics in M-channel sub-band coders, using a rate{distortion criterion. Recent research has shown that unconstrained{ length paraunitary lter banks optimized under various energy compaction criteria are principal-component lter banks and satisfy two fundamental properties: total decorrelation and spectral majorization. We present se...
متن کاملDesign of signal-adapted FIR paraunitary filter banks
We study the design of signal–adapted FIR paraunitary filter banks, using energy compaction as the adaptation criterion. We present some important properties that globally optimal solutions to this optimization problem satisfy. In particular, we show that the optimal filters in the first channel of the filter bank are spectral factors of the solution to a linear semi–infinite programming (SIP) ...
متن کاملOn reconstruction methods for processing finite-length signals with paraunitary filter banks
New expressions are developed for the perfect reconstruction of the boundary regions of a finite-length signal after subband processing. The time-invariant filter bank is required to be uniform and paraunitary, using FIR filters regardless of phase or symmetry. They accomodate a linear boundary extension in the analysis section, and avoid periodic extensions or storage of extended subband signa...
متن کاملNew Design of Orthogonal Filter Banks Using the Cayley Transform
It is a challenging task to design orthogonal filter banks, especially multidimensional (MD) ones. In the onedimensional (1D) two-channel finite impulse response (FIR) filter bank case, several design methods exist. Among them, designs based on spectral factorizations (by Smith and Barnwell) and designs based on lattice factorizations (by Vaidyanathan and Hoang) are the most effective and widel...
متن کاملNew technique for design of 2-channel fir paraunitary filter banks
In this paper we obtain a new parameterization of all FIR paraunitary two-channel filter banks. Unlike other approaches which make use of a lattice structure or a cascade algorithm, we show that our technique provides a direct explicit expression of all FIR orthogonal filters, with no need of iteration procedures. Thus, in order to design a L-tap 2-channel paraunitary filterbank, it suffices to...
