Este artigo apresenta uma avaliação de diversas técnicas de diversidade cooperativa aplicadas a futuros sistemas de transmissão multimídia digital via satélite (S-DMB). A crescente importância das redes híbridas e/ou integradas de satélite e terrestres está associada à utilização de técnicas de diversidade espacial, como a diversidade de antenas usando codificação espaço-tempo. Pode-se esperar que os esquemas de codificação espaço-tempo resultem em mais ganho de diversidade à medida que o número de antenas de transmissão aumenta. Entretanto, não podemos projetar um esquema de taxa 1 que alcance diversidade total para mais de duas antenas de transmissão. Para superar esta limitação, foram propostos esquemas quase-ortogonais, em detrimento da complexidade do decodificador e do ganho de diversidade. Neste artigo, introduzimos um esquema eficiente de codificação espaço-tempo quase ortogonal e avaliamos vários aspectos associados à aplicação do esquema proposto a sistemas de satélites. O esquema proposto neste artigo fornece a taxa total, bem como a decodificação de máxima verossimilhança por meio de detecção linear simples.

Abstract: This paper presents an evaluation of various cooperative diversity techniques applied to future satellite digital multimedia broadcasting (S-DMB) systems. The increasing importance of hybrid and/or integrated satellite and terrestrial networks is associated with the utilization of spatial diversity techniques such as antenna diversity using space-time coding. The space-time coding schemes can be expected to result in more diversity gain as the number of transmit antennas are increased. However, we cannot design a rate-1 scheme that achieves full diversity for more than two transmit antennas. To overcome this limitation, quasi-orthogonal schemes were proposed, at the expense of the decoder complexity and diversity gain. In this paper, we introduce an efficient quasi-orthogonal space time coding scheme, and evaluate various aspects associated with the application of the proposed scheme to satellite systems. The proposed scheme in this paper provides the full rate as well as maximum-likelihood decoding via simple linear detection.
