Construction of perfect space-time codes
(2013-04-29)
In this work, we propose an innovative methodology to extend the construction of minimum and non-minimum delay perfect codes as a subset of cyclic division algebras over ℚ(ζ3), where the signal constellations are isomorphic ...

Códigos de bloco espaço-temporais via corpos quadráticos
(Universidade Estadual Paulista (Unesp), 2017-01-30)
Os sistemas de comunicação com Múltiplas Entradas e Múltiplas Saídas (MIMO), são sistemas constituídos por estruturas que utilizam várias antenas, tanto no transmissor como no receptor. Por serem transmitidos via antenas, ...
Differential STBC for OFDM based Wireless Systems
(Technische Universität Hamburg-Harburg, 2007)
Broadband wireless mobile data networks are an extremely important technical topic nowadays. These networks are probably the most convenient alternative for achieving the objective of providing and increasing connectivity ...

Códigos de bloco espaço-tempo para canais mimo 2 x 2 via álgebras cíclicas de divisão
(Universidade Estadual Paulista (Unesp), 2021-05-04)
This work aims to present the construction of the Golden code, which is a perfect 2 2 space-time block code (STBC) built from a cyclic division algebra. This code is said to be perfect because it is of full rate and full ...
