Abstract

do canal nos canais que causam um erro aleatório eódigo convolucional puncionado a taxa compatível (ão (ARQ). Em um processo de decodificação de uma pluralidade de pacotes de informação dada, o processo de prevenção de erro inclui as etapas de a) decodificação de uma das pluralidades de pacotes, b) te a decodificação na etapa a), c) decodificação de uma combinação dos pacotes a partir das etapas a) e b) ou um terceiro pacote quando ocorre um erro na etapa b), e d) repetição da etapa c) até que não ocorra mais o erro de decodificação. O processo de ambos processos ARQ Tipo-1 e Tipo-2. Portanto, pode-se obter constante produtividade do canal no canal contendo erro por ruptura, no canal contends de erro coexistem simultaneamente.
