Prime fuzzy ideals over noncommutative rings

G Navarro, O Cortadellas, FJ Lobillo - Fuzzy Sets and Systems, 2012 - Elsevier
In this paper we introduce prime fuzzy ideals over a noncommutative ring. This notion of
primeness is equivalent to level cuts being crisp prime ideals. It also generalizes the one …

[HTML][HTML] Lattices from maximal orders into quaternion algebras

C Alves, JC Belfiore - Journal of Pure and Applied Algebra, 2015 - Elsevier
We propose an algebraic framework to construct dense lattices from maximal orders of a
quaternion algebra whose center is an imaginary quadratic field. This work extends [21] …

Generalized silver codes

KP Srinath, BS Rajan - IEEE transactions on information theory, 2011 - ieeexplore.ieee.org
For an nt transmit, nr receive antenna system (nt× nr system), a full-rate space time block
code (STBC) transmits at least nmin= min (nt, nr) complex symbols per channel use. The …

Method and system for WDM transmission with chromato-temporal encoding

GRB Othman, Y Jaouen, B Thedrez… - US Patent 9,036,997, 2015 - Google Patents
A transmitter and a receiver for an optical telecommunication system of the WDM type are
disclosed. In one aspect, the transmitter uses a chromato-temporal encoder which, with each …

Optimal Space-Time Block Code Designs Based on Irreducible Polynomials of Degree Two

C Alves, EM Moro - arXiv preprint arXiv:1901.06200, 2019 - arxiv.org
The main of this paper is to prove that in terms of normalized density, a space-time block
code based on an irreducible quadratic polynomial over the Eisenstein integers is an …
