Abstract

"GERENCIAMENTO DE CANAL DE CóDIGO EM UM SISTEMA DE COMUNICAçãO SEM FIO". Trata-se de sistemas e técnicas referentes a comunicações. Os sistemas e técnicas envolvem dividir uma pluralidade de estações de assinante em uma pluralidade de grupos, atribuir uma pluralidade diferente de códigos ortogonais a cada um dos grupos, o número de códigos ortogonais atribuídos a um dos grupos sendo menor que o número de estações de assinante em um dos grupos, codificar as comunicações para uma das estações de assinante em um dos grupos a uma taxa de dados e determinar se se vai espalhar pelo menos uma parte das comunicações para uma das estações de assinante com um dos códigos ortogonais atribuídos a um dos grupos como uma função da taxa de dados.
