15 صفحه اولSignal Matched Non-uniform Filter Bank
In this paper we present a non-uniform `filter bank (NUFB) matched to a given signal. To obtain matched M-channel NUFB, first, we choose the decimation set having M-down sampling/decimation factors for which perfect reconstruction NUFB exist and then using novel approach proposed in this paper, M-channel signal matched analysis bank is estimated. The outputs of all filters at the analysis side ...
متن کاملEFFICIENT NON−UNIFORM FILTER−BANK EQUALIZER (WedAmPO2)
An efficient realization of a low delay filter−bank will be proposed, which can be regarded as a filter−bank used as equalizer with either fixed or time−varying spectral gain factors. The proposed filter−bank equalizer (FBE) results in a time−domain filter whose coefficients are adapted in the (short−term) spectral−domain. Perfect signal reconstruction is obtained for a broad class of spectral ...
متن کاملCosine Modulated Non-Uniform Filter Bank with Improved Computational Efficiency
In this correspondence, a simple design method for multirate near perfect reconstruction (NPR) integer decimated filter bank with non-uniform frequency spacing and linear phase property, that involves optimization of only single parameter, is proposed. It is derived from the uniform cosine modulated filter bank (CMFB) by merging some relevant band pass filters. The design procedure and the stru...
متن کاملA low bit rate speech coder based on Gaussian adaptivewaveletsShubha
A low bit rate speech coder based on Gaussian adaptive wavelets is described. This speech coder ameliorates the problem of using two diierent mother wavelets to model voiced and unvoiced sounds as mentioned in. 1 In addition, it has been demonstrated in this paper, that Gaussian adaptive wavelets are better suited to model both voiced and unvoiced sounds as compared to Morlet and Daubechies' wa...
