Abstract

"SISTEMA, MéTODO E EQUIPAMENTO PARA GERAR UM SINAL DE TEMPORIZAçãO". Um método de comunicação sem fio de acordo com uma modalidade da invenção inclui obter uma primeira base de tempo (como, por exemplo, obter uma fase de código) de um sinal recebido de um transmissor terrestre (como, por exemplo, uma estação base CDMA). Um offset predeterminado baseado em pelo menos um retardo de propagação do sinal recebido é aplicado à primeira base de tempo, de modo a se obter uma segunda base de tempo. Por exemplo, a segunda base de tempo pode ser alinhada com a base de tempo de um sistema de satélite de posicionamento (como, por exemplo, o GPS NAVSTAR). é gerado um sinal de temporização que tem uma fase de código baseada na segunda base de tempo.
