In this paper a new union bound on the bit error probability of bit-interleaved space-time (BI-ST) coded systems is derived. Unlike existing performance analysis tools for BI-ST systems, the new bound provides a general framework for analyzing the performance of BI-ST systems employing finite interleaver sizes. The derivation is based on the uniform interleaving assumption of the coded sequence...
the decomposition $gamma=bh$ of a group $gamma$ into a subset $b$ and a subgroup $h$ of $gamma$ induces, under general conditions, a group-like structure for $b$, known as a gyrogroup. the famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary operation given by t...
Magnetic Hopfions are localized magnetic solitons with a non-zero 3D topological charge (Hopf index). Here we present an analytical calculation of the Hopfion gyrovector and show that it does not vanish even in infinite sample. The method is based on concept emergent field. particular case simplest non-trivial toroidal Hopf index |QH|=1 cylindrical dot considered dependencies components sizes c...
In the field of smart space, due to the development of technology for remote sensing, monitoring, a vast volume of spatial data is accumulated. However, there have many problems of discovering meaningful knowledge from the spatial data. Consequently, in this paper, a scientific and effective method that spatial information is intelligently processed in smart space by BI was put forward. It desc...
Let Ω be a connected compact Hausdorff space and X a Banach space for which the strong Banach-Stone property is valid. We give a complete characterization of the generalized bi-circular projection on the Banach spaces C(Ω) and C(Ω, X). We show that in each case generalized bi-circular projections are bi-contractive. We also give some results concerning projections in the convex hull of two or m...
A bi-Hamiltonian hierarchy of complex vector soliton equations is derived from geometric flows of non-stretching curves in the Lie groups G = SO(N + 1), SU(N) ⊂ U(N), generalizing previous work on integrable curve flows in Riemannian symmetric spaces G/SO(N). The derivation uses a parallel frame and connection along the curves, involving the Klein geometry of the group G. This is shown to yield...
The Dark Energy Survey (DES) collaboration will study cosmic acceleration with a 5000 deg griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM) system will be used to process and archive these data and the resulting science ready data products. The DESDM system consists of an integrated archive, a processing framework, an ensemble of astronomy codes an...
