Abstract
Un método para recibir una senal digital de radiodifusión de audio FM incluyendo una primera pluralidad de sub-portadoras en una banda lateral superior de un canal de radio y una segunda pluralidad de sub-portadoras en una banda lateral del canal de radio comprende los pasos de mezclar la senal digital de radiodifusión de audio con una senal de oscilador local para producir una senal de frecuencia intermedia, pasando la senal de frecuencia intermedia a través de un filtro paso de banda para producir una senal filtrada, determinando si una de las bandas laterales superior e inferior de la senal digital de radiodifusión de radio está contaminada, y ajustando la senal de oscilador de frecuencia local para cambiar la frecuencia de frecuencia intermedia de manera tal que el filtro paso banda elimine las sub-portadoras en la banda superior o inferior que ha sido contaminada. También se suministra un receptor que procesa una senal digital de radiodifusión de audio de acuerdo con el método.
