Gaussian matrix elements of the operator X: Reduction to confluent hypergeometric functionsA new method has been proposed for calculating the Gaussian matrix elements of the interaction operator represented by an arbitrary degree of interelectron distance X. The method is based on the expansion of two...
However, channel estimation in large-scale MIMO is said to be hampered by the pilot contamination effect, constitute a major reduction for overall system performance. In this paper, we present a novel approach which tackles this problem by enabling a covariance formulation between cells during the...
The remainder of the paper is structured as follows. The next Section presents a brief overview of the rich body of related literature. Then, in section “Robust method of MGIN reduction” the structure of the classic NLM is described. Afterwards, the robust measure of similarity between patche...
progress has been made in [CET23], where it is shown that the equation is logarithmically superdiffusive, and in [CETar], where the large-scale behaviour in the weak coupling scaling is determined. In both articles, the tools adopted are closer to...
This function is used to solve the system of linear equations of any order N, It does the same work as A\b, It user Gaussian Elimination Algorithm, that is, making the elements of lower triangle matrix zero, using the basic row transformation. This is one of the methods for fin...
In the typical lattice process of Gaussian Markov random field (GMRF), the focus is on the precision matrix, which is the inverse of the variance-covariance matrix, and the reduction of the calculation load is carried out (Rue and Held, 2005). Unlike the variance-covariance matrix, the prec...
TheGaussian Pyramidblock computes Gaussian pyramid reduction or expansion to resize an image. The image reduction process involves lowpass filtering and then downsampling the image pixels. The image expansion process involves upsampling and then lowpass filtering the image pixels. You can also use this...
Security reduction It is conceivable that the types of attack that eavesdroppers may apply on a multi-link quantum network can be more complex than the way they would attack conventional one-link protocols. For instance, in a quantum network a subset of the links that form the route from Alic...
8.12): in the case of gamut extension γ is a positive constant and in the case of gamut reduction it is negative. The motivation for the form of these kernels is given in what follows. We saw in Chapter 7 how the original LHE model of [48] could be extended by modifying the energy...
The bug can be triggered by any matrix where the row reduction hits a zero (or near-zero) value on the diagonal. The example matrix above has a perfectly fine inverse, as can be demonstrated in e.g. octave: octave:1> mx = [-2, -1, -6, -1; 6, 3, 6, -1; -3, -2, 12...
