Abstract

MéTODO E APARELHO PARA RECUPERAçãO DE PORTADORA UTILIZANDO INTERPOLAçãO DE FASE COM ASSISTêNCIA. Em um receptor, um estimador de fase baseado em decisão é usado em conjunto com um interpolador para prover uma estimativa de fase para uso na recuperação de portadora. Por exemplo, um receptor compreende um estimador de fase piloto, um loop Costas e um controlador de interpolação. O estimador de fase piloto provê estimativas de fase predeterminadas nos tempos piloto e o controlador de interpolação provê estimativas de fase interpoladas em outros tempos como uma função de uma interpolação linear com base em uma estimativa de fase determinada respectiva e pelo menos uma estimativa de erro de fase baseada em decisão a partir do loop Costas.
