Abstract
"MéTODO E APARELHO PARA GIRAR UMA FASE DE UM SINAL MODULADO". Técnicas para ajustar a rotação de fase de um sinal modulado para compensar a rotação de fase introduzida por elementos de circuito associados com o percurso do sinal de transmissão. Os elementos de circuito podem estar localizados diretamente em, ou operativamente acoplados a, o percurso do sinal de transmissão. Uma rotação de fase correspondendo a um estado de operação definido pelo(s) sinal(is) de controle recebido(s) é, então, determinada, e a fase do sinal modulado é girada por uma quantidade relacionada com a rotação de fase determinada. A compensação da rotação de fase pode ser realizada em vários locais ao longo do percurso do sinal de transmissão por rotação de cada um dos dados, das seq³ências de PN usadas para espalhar espectralmente os dados, ou dos sinais de portadora usados para modular os dados.
