Abstract

<B>CODIFICAçãO DE MúLTIPLOS NìVEIS COM DIVERSIDADE DE TEMPO<D> é fornecido um esquema de modulação codificado em múltiplos níveis no qual uma primeira parte de dados de entrada é codificada por um código de primeiro nível e uma segunda parte de dados de entrada é codificada por um código de segundo nível, o código de segundo nível sendo tal que o código de múltiplos níveis global apresenta um nível desejado de diversidade de tempo de pelo menos 2 e a distância mínima do código global não é aumentado em virtude da presença do código de segundo nível.
