Abstract

"PROCESSO DE TRANSMITIR INFORMAçãO, SISTEMA DE TRANSMISSãO DE DIVERSIDADE PARA TRANSMITIR INFORMAçãO, PROCESSO DE RECEBER INFORMAçãO, E, TERMINAL DE USUáRIO PARA RECEBER INFORMAçãO" Um processo de transmitir informação compreende as etapas de mapear uma palavra de informação a primeira e segunda palavras de código usando primeira e segunda funções de mapeamento, e transmitir a primeira e segunda palavras de código. A palavra de informação é selecionada de um conjunto de palavras de informação com cada uma das palavras de informação no conjunto de palavra de informação tendo um primeiro comprimento predeterminado, e a primeira palavra de código é selecionada de um conjunto de palavras de código com cada uma das palavras de código no conjunto de palavra de código tendo um segundo comprimento predeterminado maior que o primeiro comprimento predeterminado. A segunda palavra de código é selecionada do conjunto de palavra de código, e a primeira e segundo funções de mapeamento são definidas tal que cada uma das palavras de informação do conjunto de palavra de informação é mapeada a duas palavras de código diferentes do conjunto de palavra de código. Sistemas e terminais relacionados também são discutidos.
