Abstract

"MéTODO E EQUIPAMENTO DE DECODIFICAçãO TURBO PARA COMUNICAçõES SEM FIO". Em um sistema de comunicação 10, um método e equipamento fornecem a decodificação de uma seqüência de símbolos de dados turbo codificados. Os nós de canal R~ x~, R~ y~, R~ z~, são atualizados com base em uma saída de canal recebida, e as mensagens de saída dos nós de símbolo (701, 707, 708) são inicializadas. Os nós de símbolo (701, 707, 708) estão em comunicação com os nós de canal R~ x~, R~ y~ e R~ z~. As atualizações dos nós de computação C (704) e D (706) em diferentes ocorrências no tempo são realizadas de acordo com uma programação de acionamento.
