A Novel Multi-User Detection on LS in Impulse Radio UWB Systems

工程科学与技术, 2009
: In this paper, firstly, changes the systems of time-hopping BPSK in UWB into a virtually linear model, secondly， writes least square criterion , one of the optimal criterion of adaptive filtering algorithm, into matrix form, and proposes a new ...

New Bounds for the Davis–Wielandt Radius via the Moore–Penrose Inverse of Bounded Linear Operators

Axioms
In this paper, we obtain some new upper bounds involving powers of the Davis–Wielandt radius of bounded linear operators with closed ranges by using the Moore–Penrose inverse.

The Moore-Penrose inverse of a morphism with factorization

, 1981
Given an m-by-n matrix A of rank r over a field with an involutory automorphism, it is well known that A has a Moore-Penrose inverse if and only if rank A∗A=r= rank AA∗.

An Investigation on Mathematical Modeling of Operators on The Hilbert Domain subjected to The Equality Theory

Journal of Applied Science and Engineering
This work begins by presenting the essential and enough circumstances for the presence of the Hermitian solution to equations ΨXΦ + Φ∗YΨ∗ = Ω = Ψ∗XΦ∗+ ΦYΨ in the case where the operators are linear and bounded in a Hilbert space and in terms of the Moore-

The Moore-Penrose inverse over a commutative ring

, 1992
Let R be a commutative ring with 1 and with an involution a → ā, and let MR be the category of finite matrices over R with the involution (aij) → (aij)∗ = (āji).

The Moore-Penrose Inverse in Art [PDF]

, 2020
The "Moore-Penrose inverse" of a matrix A corresponds to the (unique) matrix solution X of the system AXA=A, XAX=X, (AX) T =AX, (XA) T =XA.

RECTANGULAR INPUT-OUTPUT MODELS BY MOORE-PENROSE INVERSE

Rect@, 2014
The official available data must be the primary datasource in economic studies. However, in economic modelling related with supply-use tables this aspect is ignored.

A New High-Order Stable Numerical Method for Matrix Inversion

The Scientific World Journal, 2014
A stable numerical method is proposed for matrix inversion. The new method is accompanied by theoretical proof to illustrate twelfth-order convergence. A discussion of how to achieve the convergence using an appropriate initial value is presented.
