On efficient implementation of oversampled linear phase perfect reconstruction filter banks

چکیده
In this paper, we first present an alternative way of generating oversampled linear phase perfect reconstruction filter banks (OSLPPRFB). We show that this method provides the minimal factorization of a subset of existing OSLPPRFB. The combination of the new structure and the conventional one leads to efficient implementations of a general class of OSLPPRFB. Possible application of the new scheme is discussed.

Oversampled Cosine Modulated Filter Banks With Perfect Reconstruction - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on
Oversampled filter banks (FB’s) offer more design freedom and better noise immunity than critically sampled FB’s. Due to the increased computational complexity caused by oversampling, oversampled FB’s allowing an efficient implementation, such as cosine modulated filter banks (CMFB’s), are of particular interest. So far, only critically sampled CMFB’s have been considered. In this paper, we int...

In this paper, a novel technique for the design of two-channel Quadrature Mirror Filter (QMF) banks with linear phase in frequency domain is presented. To satisfy the exact reconstruction condition of the filter bank, low-pass prototype filter response in pass-band, transition band and stop band is optimized using unconstrained indirect update optimization method. The objective function is form...
متن کاملNoise robust oversampled linear phase perfect reconstruction filter bank with a lattice structure
An oversampled linear phase (LP) perfect reconstruction (PR) filter banks (FB) with a lattice structure involving the noise robust building block is presented. The structure is based on the generalized lapped pseudo-biorthogonal transform (GLPBT), which represents a large class of lapped transforms. Given an analysis bank of the GLPBT and a correlation matrix of noise, the proposed synthesis ba...

We investigate a special class of N-channel oversampled linearphase perfect reconstruction filter banks with a smaller decimation factor M than N. We deal with systems in which all analysis and synthesis filters have the same FIR length and share the same center of symmetry. We provide the general lattice factorization of a polyphase matrix of a particular class of these oversampled filter bank...
متن کاملHigher-order feasible building blocks for lattice structure of oversampled linear-phase perfect reconstruction filter banks
This paper proposes new building blocks for the lattice structure of oversampled linearphase perfect reconstruction filter banks (OLPPRFBs). The structure is an extended version of higher-order feasible building blocks for critically sampled LPPRFBs. It uses fewer number of building blocks and design parameters than those of traditional OLPPRFBs, whereas frequency characteristics of the new OLP...
