Abstract

<B>MéTODO E SISTEMA PARA GERAR UMA SEQuêNCIA COMPLEXA DE PSEUDO-RUìDO PARA PROCESSAR UM SINAL DE ACESSO MúLTIPLO DE DIVISãO POR CóDIGO<D> Em um sistema de comunicação sem fio, um tempo de chip é selecionado em um gerador de seq³ência complexa de pseudo-ruído (PN). Para um próximo tempo de chip que se segue ao tempo de chip selecionado, uma diferença de fase entre um chip PN complexo anterior e um próximo chip PN complexo está restrito a um ângulo de fase pré-selecionado. Em uma versão, cada outro tempo de chip é selecionado e o ângulo pré-selecionado é de 90 graus.
