Perfect Reconstruction Conditions and Design of Oversampled DFT-Modulated Transmultiplexers
This paper presents a theoretical analysis of oversampled complex modulated transmultiplexers. The perfect reconstruction (PR) conditions are established in the polyphase domain for a pair of biorthogonal prototype filters. A decomposition theorem is proposed that allows it to split the initial system of PR equations, that can be huge, into small independent subsystems of equations. In the orth...
متن کاملA new design algorithm for two-band orthonormal rational filter banks and orthonormal rational wavelets
In this paper, we present a new algorithm for the design of orthonormal two-band rational filter banks. Owing to the connection between iterated rational filter banks and rational wavelets, this is also a design algorithm for orthonormal rational wavelets. It is basically a simple iterative procedure, which explains its exponential convergence and adaptability under various linear constraints (...
متن کاملfB and fBs using NRQCD
This talk summarizes the quenched calculation of fB and fBs presented in [1]. The heavy quark is simulated using an O(1/M) improved NRQCD action, and the tadpole improved clover action is used for the light quarks. The axial current includes the O(1/M) corrections in one-loop perturbation theory and the O(1/M) ones at tree-level. We discuss the various systematic effects and consistency checks ...
متن کاملfBs from QCD sum rules
The decay constants of the pseudoscalar mesons B and Bs are evaluated from QCD sum rules for the pseudoscalar two-point function. Recently calculated perturbative three-loop QCD corrections are incorporated into the sum rule. An analysis in terms of the bottom quark pole mass turns out to be unreliable due to large higher order radiative corrections. On the contrary, in the MS scheme the higher...
متن کاملDesign of paraunitary oversampled cosine-modulated filter banks
In this paper we derive perfect reconstruction (PR) conditions for oversampled cosine-modulated lter banks. The results can be regarded as a generalization of the known work for critical subsampling. We show that in the over-sampled case we gain some additional degree of freedom, which can be exploited in the lter design process. This leads to PR prototypes with stopband attenuations being much...
