Abstract

La presente invención se refiere a un método (50) de búsqueda de la presencia de una señal útil, de anchura espectral ?B predefinida, en una banda de multiplexión que tiene una anchura espectral mayor que ?B, que incluye los pasos de: - (51) calcular una señal de frecuencia representativa de una densidad espectral de potencia en la banda de multiplexión; - (54) calcular una señal no útil filtrando la señal de frecuencia por medio de un filtro capaz de suprimir la totalidad o parte de las señales que tienen una anchura espectral igual a, o menor que ?B; - (56) calcular una señal de proporción de potencia, representativa de la proporción de la señal de frecuencia con respecto a la señal no útil; - (57) comparar la señal de proporción de potencia con un valor de umbral predefinido. La invención se refiere también a un producto programa de computadora, una unidad receptora y una estación (30) de un sistema (10) de telecomunicaciones digital, que comprenden dicha unidad receptora.
