Abstract

"SISTEMA DE COMUNICAçãO CDMA PARA DESIGNAR FLEXIVELMENTE CóDIGOS DE DIFUSãO DE ACORDO COM TRáFEGO". Em um sistema de comunicação CDMA usando uma banda de freq³ência comum para um canal de ida e para um canal de retorno, uma primeira seção de detecção detecta tráfego no canal de retorno para produzir um sinal indicativo do tráfego no canal de retorno. Uma primeira seção de designação (131) designa códigos de difusão de retorno para o canal de retorno. A primeira seção de designação (132) muda, em resposta ao primeiro sinal detectado, o número dos códigos de difusão de retorno. Uma segunda seção de detecção (231) detecta tráfego no canal de ida para produzir um segundo sinal detectado indicativo do tráfego no canal de ida. Uma segunda seção de designação (232) designa códigos de difusão de ida para o canal de ida. A segunda seção de designação muda, em resposta ao segundo sinal detectado, o número do código de difusão de ida.
