Abstract

Patente de Invenção: <B>"PROCESSO PARA RECEBER OU TRANSMITIR COMUNICAçõES"<D>. A utilização de seq³ências de alargamento reduzidas (spreading codes), especialmente no canal de paging, para a correlação na recepção de sinais de CDMA, possibilita providências de economia de corrente elétrica tais como, por exemplo, o desligamento intermitente de conversores A/D ou de correlacionadores. Para manter a ortogonalidade das seq³ências de alargamento, as seq³ências de alargamento utilizadas devem ser selecionadas de tal modo que na medida do possível não se correlacionam com a seq³ência de alargamento do canal de paging.
