This paper proposes a new design and implementation method for a class of multiplier-less 2-channel 1D and 2D non-separable perfect reconstruction (PR) filter banks (FB). It is based on the structure proposed by Phoong et al. and the use of multiplier block (MB). The latter technique allows one to hrther reduce the number of adders in implementing these multiplier-less FB by almost 50%, compare...

The purpose of this study was to identify factors influencing the adoption of wheat waste management by wheat farmers. The method used in this study using the spatial Probit models and Bayesian model was used to estimate the model. MATLAB software was used in this study. The data of 220 wheat farmers in Khouzestan Province based on random sampling were collected in winter 2016. To calculate Bay...

In conventional memory-based multiplication design, the multiplier is replaced by a read only memory (ROM). Since the memory size increases exponentially with the input length, in this paper, a modified hardwareefficient approach for memoryless-based multiplication is proposed. The very large scale integration (VLSI) measure indicates that the proposed approach involves less hardware complexity...

17 Abstract— An analysis is made on the computational complexity of Block Least Mean Square Adaptive Filter where the filter computation is decomposed into M sub filters and M=N/L where N is the filter size, L is the block size. The decomposition is done inorder to favour time-multiplexing of the filter output computation and weight-increment term computation of adaptive filter. This structure ...

Nowadays, researchers are paying more attention to recognize the human emotions from various modalities such as facial features, physiological or biological signals and speech signals. In the last decade, a number of research works have been carried out on emotion recognition using speech signals. In this work, emotion recognition system was developed using the features extracted from the emoti...

This paper proposes new structures for realizing 1D and circular symmetric 2D FIR filters with variable cutoff frequencies. They are based on the interpolation of the impulse responses using the Farrow structure. The coefficients of the sub-filters in the Farrow structure are represented in sum-of-powers-of-two (SOPOT) coefficients. which can easily be implemented as simple shifts and additions...

In this paper a new efficient feature extraction methods for speech recognition have been proposed. The features are obtained from Cepstral Mean Normalized reduced order Linear Predictive Coding (LPC) coefficients derived from the speech frames decomposed using Discrete Wavelet Transform (DWT). In the literature it is assumed that the speech frame of size 10 msec to 30 msec is stationary, howev...

This paper presents comparative study on recent integer DCTs and a new method to construct a low sensitive structure of integer DCT for colored input signals. The method refers to sensitivity of multiplier coefficients to finite word length as an indicator of how word length truncation effects on quality of output signal. The sensitivity is also theoretically evaluated as a function of auto-cor...

This paper presents an efficient constant multiplier architecture based on vertical-horizontal binary common subexpression elimination (VHBCSE) algorithm for designing a reconfigurable finite impulse response (FIR) filter whose coefficients can rapidly change in real time. To design an efficient reconfigurable FIR filter, according to the proposed VHBCSE algorithm, 2-bit binary common sub-expre...

We introduce the notion of Bernstein-Sato polynomial of an arbitrary variety, using the theory of V -filtrations of M. Kashiwara and B. Malgrange. We prove that the decreasing filtration of multiplier ideals coincides essentially with the restriction of the V -filtration. This implies a relation between the roots of the Bernstein-Sato polynomial and the jumping coefficients of the multiplier id...
