Abstract

<B>ESPALHAMENTO DINâMICO E INTELIGENTE PARA CDMA DE BANDA LARGA<D>. Um método para alocar utilização de múltiplas portadoreas em um sistema de transmissão de CDMA de banda larga determina, primeiramente, os níveis de utlização/interferência de portadora para cada uma das múltiplas portadoras. Com base no nível de utilização/interferência de portadora, as astribuições de portadoras são alocadas em uma base não igual. A alocação da atribuição de portadora propende a seleção das portadoras no sentido aposto das portadoras utilizadas/interferidas mais elevadas. Também é descrito um aparelho para implementar o método.
