A Low-Complexity Massive MIMO Precoding Algorithm Based on Chebyshev Iteration

open access: goldIEEE Access, 2017
Precoding algorithm is used to transmit signals effectively and to reduce the interferences from other user terminals in the massive multiple-input-multiple-output (MIMO) systems. In order to decrease the computational complexity of the precoding matrix,

Some Results on Iterative Proximal Convergence and Chebyshev Center [PDF]

open access: goldJournal of Function Spaces, 2021
In this paper, we prove a sufficient condition that every nonempty closed convex bounded pair M,N in a reflexive Banach space B satisfying Opial’s condition has proximal normal structure.

A numerically stable high-order Chebyshev-Halley type multipoint iterative method for calculating matrix sign function

open access: goldAIMS Mathematics, 2023
A new eighth-order Chebyshev-Halley type iteration is proposed for solving nonlinear equations and matrix sign function. Basins of attraction show that several special cases of the new method are globally convergent.

Chebyshev iteration methods for integral equations of the second kind. [PDF]

open access: bronzeMathematics of Computation, 1970
In this paper the numerical solution of Fredholm integral equations of the second kind using an iterative method in which the solution is represented by a Chebyshev series is discussed. A description of a technique of Chebyshev reduction of the norm of the kernel for use in cases when the iterations converge slowly or not at all is also given. Finally,

State Transition Matrix for Perturbed Orbital Motion Using Modified Chebyshev Picard Iteration [PDF]

open access: hybridThe Journal of the astronautical sciences, 2015
The Modified Chebyshev Picard Iteration (MCPI) method has recently proven to be highly efficient for a given accuracy compared to several commonly adopted numerical integration methods, as a means to solve for perturbed orbital motion.

Preconditioned Nonlinear Iterations for Overlapping Chebyshev Discretizations with Independent Grids [PDF]

open access: greenSIAM Journal on Scientific Computing, 2020
The additive Schwarz method is usually presented as a preconditioner for a PDE linearization based on overlapping subsets of nodes from a global discretization. It has previously been shown how to apply Schwarz preconditioning to a nonlinear problem.

ON THE STABILITY OF THE CHEBYSHEV ITERATIVE METHOD

open access: diamondDYNAMICS OF SYSTEMS, MECHANISMS AND MACHINES, 2023
Numerical solution of the systems of linear equations (linear system), especially in case of nonstationary problems, takes a significant part of computer time. Normally, for solving linear system the applied program packages use either Chebyshev iterative method (wave linear problems etc.), which requires setting the optimal parameter, or gradient ...

A Higher Order Chebyshev-Halley-Type Family of Iterative Methods for Multiple Roots [PDF]

open access: goldMathematics, 2019
The aim of this paper is to introduce new high order iterative methods for multiple roots of the nonlinear scalar equation; this is a demanding task in the area of computational mathematics and numerical analysis. Specifically, we present a new Chebyshev&
