Abstract

AQUISIçãO DE SINAL EM COMUNICAçõES DE ESPECTRO ESPALHADO PAR-A-PAR São descritos métodos e estações móveis para transmissão, recepção e processamento de sinais de comunicação par-a-par sem uma estação base ou elemento de rede. Uma estação móvel transmissora pode alternar duas ou mais máscaras de código longo para gerar um ou mais códigos de ruído pseudo-aleatório (PN) para espalhar dados para transmissão. Uma estação móvel receptora recebe os dados espalhados e obtém sincronização com a estação móvel transmissora.
