Os códigos turbo espaço-tempo têm vantagens dos códigos espaço-temporais e dos códigos turbo, e o código turbo espaço-tempo proposto por Su e Geraniotis é conhecido por atingir taxa de codificação total e diversidade total de antenas. Este artigo apresenta algumas melhorias em seu código turbo espaço-tempo em uma configuração de duas antenas. Primeiro propomos uma nova condição para diversidade total de antenas que impõe menos restrições ao intercalador. Em seguida, aplicando um método usado para melhorar a modulação codificada em treliça turbo ao código turbo espaço-tempo, propomos um novo algoritmo de decodificação que utiliza estimativas mais precisas sobre informações extrínsecas. Os resultados da simulação mostram que a condição proposta garante total diversidade de antenas e o novo algoritmo de decodificação proporciona um desempenho melhor que o de Su e Geraniotis.

Abstract: Space-time turbo codes have both advantages of space-time codes and turbo codes, and the space-time turbo code proposed by Su and Geraniotis is known to achieve full coding rate and full antenna diversity. This paper presents some improvements of their space-time turbo code in a two-antenna configuration. We first propose a new condition for full antenna diversity which imposes less constraints on the interleaver. Next, by applying a method used to improve turbo trellis-coded modulation to the space-time turbo code, we propose a new decoding algorithm which utilizes more precise estimates on extrinsic information. Simulation results show that the proposed condition assures full antenna diversity and the new decoding algorithm provides a better performance than that of Su and Geraniotis'.
