Abstract

APARELHO E MéTODO PARA TRANSMITIR UM SINAL DE SUB-CANAL EM UM SISTEMA DE COMUNICAçãO QUE UTILIZA UM ESQUEMA DE ACESSO MúLTIPLO POR DIVISãO DE FREQüêNCIA ORTOGONAL Um método de alocar padrões de entrelaçamento de sinal de sub-canal para estações base (BSs) que formam um sistema de comunicação sem fio capaz de dividir uma banda de freqüência em uma pluralidade de sub-portadoras e incluir uma pluralidade de sub-canais. O método compreende as etapas de criar uma seqüência ortogonal básica tendo um comprimento idêntico a um número das sub-portadoras que formam o sub-canal; criar pluralidade de seqüências tendo comprimento idênticos ao comprimento da seqüência ortogonal básico por um de deslocamento cíclico da seqüência ortogonal básica e através de efetuar uma operação módulo com base em um número de sub-portadoras que formam o sub-canal, após acrescentar um recuo predeterminado na seqüência ortogogal básica; selecionar um número predeterminado de seqüências que correspondem ao número das BSs; e alocar as seqüências alocadas como os padrões de entrelaçamento de sinal de sub-canal para as BSs.
