Design of perfect reconstruction FIR multifilters
نویسنده
چکیده
The design of perfect reconstruction FIR multi lters is discussed in this paper. Schur algorithm is applied to factorize the polyphase matrix of multi lters into lattice blocks. The multi lters are characterized by the chain parameters in each lattice block. The complete parameterization of paraunitary multi lters and a class of biorthogonal multilters are derived. The parameterizations are minimial and result in simple design methods using unconstrainted optimization.

Design of Biorthogonal FIR Linear Phase Filter Banks with Structurally Perfect Reconstruction
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 reconstruction condition. However, quantization of the filter coefficients results in some errors in the frequency response, so it is not guaranteed that the perfect reconstruction condition is still satisfied. In this paper, we pr...
متن کاملFIR approximations of inverse filters and perfect reconstruction filter banks
This paper first describes an algorithm that finds the approximate finite impulse response (FIR) inverse of an FIR filter by minimizing the inversion (or reconstruction) error constrained to zero-bias. The generalization of the inverse filtering problem in the two channel case is the design of perfect reconstruction filter banks that use critical sampling. These considerations lead to the deriv...
متن کاملOn the Design of Near-Perfect-Reconstruction IIR QMF Banks Using FIR Phase-Compensation Filters
In this paper we describe a novel approach for the design of near-perfect-reconstruction mixed FIR/ allpass-based quadrature mirror filter banks. The design is carried out in the polyphase domain, where FIR filters, obtained via simple closed-form expressions, are employed for compensating the non-linear phase introduced by the allpass filters. Starting from a generalized two-band structure, we...
متن کاملTwo-channel perfect-reconstruction FIR QMF structures which yield linear-phase analysis and synthesis filters
Abstruct-Among all cases of two-channel FIR perfect-reconstruction QMF structures which yield linear-phase filters, only two cases yield good filters in the practical sense. In this paper, lattice-type structures are derived for both cases-to structurally enforce the perfect-reconstruction and linear-phase properties simultaneously. The structure in the first case is related to the linear predi...
متن کاملFilter design for MIMO sampling and reconstruction
We address the problem of FIR equalizer filter design for multiple-input multiple-output (MIMO) linear time-invariant channels with uniform sampling at the channel outputs. This scheme encompasses Papoulis’ generalized sampling and several nonuniform sampling schemes as special cases. The input signals are modeled as either continuous-time or discrete-time multi-band input signals, with differe...
