In this paper we propose a transmission concept that improves the performance of high rate non-orthogonal space-time block codes. Orthogonal space-time codes have well known rate limitations [9], [7]. If the symbol rate is increased beyond those limits either code orthogonality [5] or the effective diversity gain is necessarily compromised. In the presence of channel coding the performance of n...

Sankeralli and Mullen (2001) argue that the relationship between lights and neural mechanisms depends on which color space is used. In particular, they dispute what they term the ‘orthogonality property’, according to which modulation of lights orthogonal to the direction of a linear mechanism is invisible to the mechanism. They maintain that the orthogonality property is not valid for any arbi...

We offer a new definition of $varepsilon$-orthogonality in normed spaces, and we try to explain some properties of which. Also we introduce some types of $varepsilon$-orthogonality in an arbitrary  $C^ast$-algebra $mathcal{A}$, as a Hilbert $C^ast$-module over itself, and investigate some of its properties in such spaces. We state some results relating range-kernel orthogonality in $C^*$-algebras.

Abstract-A half-range orthogonality theorem concerning the established elementary solutions of the two-group neutron transport equation for isotropic scattering and plane geometry is proved. The orthogonality relations are based on a Chandrasekhar-type H-matrix, and all necessary normalization integrals are evaluated so that the desired expansion coefficients may be expressed concisely in terms...

In this paper, we consider the concepts co-farthest points innormed linear spaces. At first, we define farthest points, farthest orthogonalityin normed linear spaces. Then we define co-farthest points, co-remotal sets,co-uniquely sets and co-farthest maps. We shall prove some theorems aboutco-farthest points, co-remotal sets. We obtain a necessary and coecient conditions...

Orthogonality plays a fundamental role in various mathematical theorems and in physics. The orthogonal eigenfunctions that represent the intrinsic motions of various physical systems can also be regarded as transverse wave modes in a straight waveguide. Because of their orthogonality, these modes propagate independently, without mutual interference. When the wall separation fluctuates, the form...
