Abstract

Un sistema de compensación de deriva de frecuencia para un radiorreceptor incluye un generador de señal piloto que está configurado para generar dos señales piloto, un oscilador local que está configurado para generar una señal de frecuencia de oscilador local, un primer mezclador que genera una primera señal piloto de desplazamiento, un segundo mezclador que genera una segunda señal piloto de desplazamiento, y una sumadora que está configurada para agregar la primera señal piloto de desplazamiento y la segunda señal piloto de desplazamiento a la señal de frecuencia intermedia para obtener una señal compuesta; el sistema de compensación de deriva de frecuencia incluye un procesador que está configurado para detectar deriva de frecuencia en la señal piloto de desplazamiento en respuesta a la señal compuesta y para generar una señal de control de deriva de frecuencia para compensar la deriva de frecuencia; se describen radiorreceptores, receptores GPS, y métodos relacionados.
