Abstract

Patente de invenção: <B>"PROCESSO PARA A SINCRONIZAçãO DE UMA ESTAçãO RáDIO BASE COM UMA ESTAçãO MóVEL".<D> Processo para a sincronização de uma estação rádio base com uma estação móvel por meio de uma seq³ência de sinais, que pode ser obtida de seq³ências parciais de sinais pelo fato de que uma segunda seq³ência parcial de sinais é repetida, e nisto, é modulada por uma primeira seq³ência parcial de sinais, sendo que a primeira e a segunda seq³ência parcial de sinais possuem o mesmo comprimento.
