Abstract

Se detecta una señal de sincronización de red con una ubicación de frecuencia desconocida muestreando la señal recibida sobre una banda de interés en frecuencia, y durante el período de repetición de la señal de sincronización en el tiempo. La señal se convierte al dominio de frecuencia. Las subbandas de la señal de dominio de frecuencia, que corresponden a diferentes ubicaciones de sincronización posibles y desplazamientos de frecuencia, se extraen y se convierten al dominio de tiempo, en donde se busca la señal de sincronización a lo largo de la ventana de recepción usando un filtrado coincidente en el dominio de tiempo.
