Abstract

La presente proporciona un método para reducir la interferencia en radiofrecuencia en un receptor de emision de audio digital en canal en banda de FM. El método comprende las etapas de recibir una senal compuesta que incluye una senal de interés y una senal de interferencia, demodular la senal compuesta para producir una primera senal demodulada, computar una primera decision transitoria binaria a partir de la primera senal demodulada, procesar la senal compuesta para producir una senal procesada, demodular la senal procesada para producir una segunda senal demodulada, computar una segunda decision transitoria binaria a partir de la segunda senal demodulada, y combinar la primera decision transitoria binaria y la segunda decision transitoria binaria para producir una senal de salida. También se incluyen los receptores que utilizan el método arriba senalado.
