Design of Micro-strip Symmetrical Dual-band Filter Based on Wireless Sensor Network Nodes
EURASIP Journal on Wireless Communications and Networking, 2019 The micro-strip antenna filter design of wireless sensor network nodes is usually used to improve the out-of-band suppression and frequency selectivity by increasing the order of the filters, but the filters are usually single band, not only the size is ...

New fast algorithms for polynomial interpolation and evaluation on the Chebyshev node set
Computers & Mathematics with Applications, 1998 Let \(A=\{\cos((2k+1)/(2n+2))\pi \}_{k=0,\ldots,n}\), the author proves the following results: interpolation to a polynomial of a degree at most \(n\) on the node set \(A\) can be performed by using \(O(n\log n)\) arithmetic operations; a polynomial of degree at most \(n\) can be evaluated on the node set \(A\) at the cost of \(O(n\log n)\) arithmetic ...

Journal of Inequalities and Applications, 1999 For a fixed integer \(m\geq 0\) and \(1\leq K\leq n\), let \(A_{k,2m,n} (T,x)\) denote the \(k\)th fundamental polynomial for \((0,1, \dots, 2m)\) Hermite-Fejér interpolation on the Chebyshev nodes \(\{x_{j,n}= \cos[(2j-1)\pi/ (2n)]\): \(1\leq j\leq n\}\). So \(A_{k,2m,n} (T,x)\) is the unique polynomial of degree at most \((2m+1)n-1\) which satisfies \

Matrix method and the suppression of Runge's phenomenon
SciPost Physics CoreHigher-degree polynomial interpolations carried out on uniformly distributed nodes are often plagued by overfitting, known as Runge's phenomenon. This work investigates Runge's phenomenon and its suppression in various versions of the matrix method for ...
