On parameter filtering in continuous subword-unit-based speech recognition [PDF]

open access: yes, 1996
Simple IIR or FIR filters have been widely used in isolated or connected word recognition tasks to filter the time sequence of speech spectral parameters, since, despite their simplicity, they significantly improve recognition performance. Those filters,

Noniterative Design of 2-Channel FIR Orthogonal Filters

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
This paper addresses the problem of obtaining an explicit expression of all real FIR paraunitary filters. In this work, we present a general parameterization of 2-channel FIR orthogonal filters.

Design of Low-Power Multiplierless Linear-Phase FIR Filters

open access: yesIEEE Access, 2017
In the design of multiplierless finite impulse response (FIR) filters, tremendous efforts have been made to reduce the number of adders of the multiplier block for the reduction of overall chip area and power consumption. However, fewer in the multiplier

Automated design of low complexity FIR filters [PDF]

open access: yes, 1998
This paper considers the design of low complexity FIR filters. Complexity is reduced by constraining the filters to have integer coefficients, which can be efficiently implemented using primitive operator directed graphs (PODG).

Power Efficient Design of Parallel/Serial FIR Filters in RNS [PDF]

open access: yes, 2012
It is well known that the Residue Number System (RNS) provides an efficient implementation of parallel FIR filters especially when the filter order and the dynamic range are high.

Fast implementation of a general L/M rate changer by a filter bank structure [PDF]

open access: yes, 2001
In this paper, we show that an L/M rate changer can be realized as a discrete time SISO (L,M) shift invariant system in form of a two-dimensional kernel function or a filter bank structure.

LOW COST APPROXIMATE ADDER SUBTRACTOR FOR FIR FILTER

open access: yesJournal of Engineering, 2003
The cost of the FIR filter depends on the cost of its components that are classified into three types namely buffer, multiplier and adder/subtractor.The adder/subtractor cover the most FIF.

Alias-free, real coefficient m-band QMF banks for arbitrary m [PDF]

open access: yes, 1987
Based on a generalized framework for alias free QMF banks, a theory is developed for the design of uniform QMF banks with real-coefficient analysis filters, such that aliasing can be completely canceled by appropriate choice of real-coefficient synthesis

SSA of biomedical signals: A linear invariant systems approach [PDF]

open access: yes, 2010
Singular spectrum analysis (SSA) is considered from a linear invariant systems perspective. In this terminology, the extracted components are considered as outputs of a linear invariant system which corresponds to finite impulse response (FIR) filters ...
