Abstract

transferência sincronizada de dados de sequenciamento em um sistema de antenas distribuído.modalidades da invenção fornecem um método, sistema de antenas distribuído (50), e componentes que geram um sinal de relógio de oscilação reduzida a partir de uma sequência de dados binários codificados em série transmitidos através de um meio de comunicação (60,60a e, 66). o método compreende o recebimento de um sinal modulado que inclui a sequência de dados binários codificados e a extração da sequência de dados binários codificados. o método compreende adicionalmente a geração de um sinal de relógio recuperado (92,1,12,206) que é travado em fase na sequência de dados binários codificados, gerando um sinal de erro (verror) com base em uma diferença entre uma fase da sequência de dados binários codificados e o sinal de relógio recuperado (92,112, 206), e integrando o sinal de erro (verror) para gerar um sinal (vcontrol) para controlar um oscilador de voltagem controlada (70,216,216a a c, 258). o método compreende adicionalmente a geração de um sinal de relógio recuperado estável (95, 208) e produzindo pelo menos um relógio de saída (224) pelo escalonamento da frequência do sinal de relógio recuperado estável (95,208).
