Abstract

DISPOSITIVO DE TRANSMISSãO DE MúLTIPLAS PORTADORAS E MéTODO DE TRANSMISSãO DE MúLTIPLAS PORTADORAS. A presente invenção refere-se a um dispositivo de transmissão de múltiplas portadoras capaz de melhorar a razão de erro do pacote em um sistema onde os dados de transmissão são repetidamente transmitidos por múltiplas portadoras. Nesse dispositivo, os dados de transmissão são submetidos à codificação da correção de erro em uma unidade de codificação de correção de erro (102), modulação em uma unidade de modulação (104) e repetição em uma unidade de repetição (106). Um sinal depois da repetição (bit de repetição) é mapeado de modo bidimensional no domínio de freqüência e no domínio de tempo de acordo com um padrão predeterminado em uma unidade de mapeamento (108). A energia de transmissão do bit de repetição é controlada de modo que o valor total da energia de transmissão do bit de repetição que constitui um bit seja idêntico a todos os bits e o bit de repetição de qualidade de recepção preferível tenha uma grande energia de transmissão enquanto o bit de repetição de má qualidade de recepção tenha uma pequena energia de transmissão.
