Nos últimos anos, o método de codificação em bloco espaço-tempo (STBC) tem atraído atenção por fornecer diversidade de transmissão em sistemas de comunicação móvel. Embora o método STBC seja muito eficaz em ambientes com desvanecimento lento, seu desempenho em ambientes com desvanecimento rápido ainda não foi claramente verificado. Neste artigo propomos um sistema de radiocomunicação ferroviária utilizando codificação espaço-temporal em cooperação com duas estações base. Aqui, consideramos o método diferencial STBC (D-STBC) no sistema de comunicação ferroviária para superar as dificuldades causadas pelo ambiente de desvanecimento rápido. Comparamos o desempenho do método STBC e D-STBC onde há deslocamento de frequência entre duas estações base. Além disso, apresentamos o resultado da simulação do desempenho geral do sistema, incluindo deslocamento de frequência e atraso de transmissão ao operar o método D-STBC. A avaliação geral deste artigo mostra que o método D-STBC é adequado para a realização de sistemas de comunicação ferroviária altamente confiáveis.

Abstract: In recent years, the space-time block coding (STBC) method has attracted attention to provide transmission diversity in mobile communication systems. Although the STBC method is very effective in slow fading environments, its performance in fast fading environments has yet to be clearly verified. In this paper we propose a railway radio communication system using space-time coding in cooperation with two base stations. Here, we considered the differential STBC (D-STBC) method in railway communication system to overcome difficulties caused by the fast fading environment. We have compared the performance of STBC and D-STBC method where there is frequency offset between two base stations. Moreover, we have presented the simulation result of overall performance of the system including frequency offset and transmission time delay when operating D-STBC method. The overall evaluation on this paper shows that the D-STBC method is suitable for realizing highly reliable railway communication systems.
