Abstract

Patente de Invenção: "DETECTOR TOLERANTE DE DESALINHAMENTO DE FREQuêNCIA". Um método para separar dados transmitidos em paralelo em freq³ências arbitrárias em um canal inclui: uma separação de um sinal de um canal em uma pluralidade de lotes representando subcanais, cada lote tendo uma freq³ência de lote (902); a geração de uma freq³ência travada, pela aplicação de um laço de fase travada (PLL) a cada subcanal (904); a determinação de uma diferença entre a freq³ência travada e a freq³ência de lote (906); e a correlação do sinal com uma diferença entre a freq³ência travada e a freq³ência de lote (910).
