Abstract

Un dispositivo de radiocomunicación, que transmite o que recibe una señal a una frecuencia de portadora predeterminada. El dispositivo incluye un oscilador de referencia (24), que genera una frecuencia de reloj que tiene un error de frencuencia de reloj con relación a una frecuencia especificada del mismo, un procesador (22) que estima el error de frecuencia de reloj y descompone el error para determinar componentes aproximada y fina corrección de error, al menos un sintetizador de frecuencia (54, 56, 58,) que responde a la frecuencia de reloj y a la componente de corrección de error aproximada, genera una frecuencia parcialmente corregida con un error de frecuencia residual, cuya frecuencia parcialmente corregida es aplicada para tratar la señal, y circuiteria (27) de tratamiento en banda de base, que aplica la componente fina de corrección de frecuencia residual.
