Abstract

Procedimiento para la sincronización de varios sistemas de transmisión por radio, que constan, en cada caso, al menos de una estación de base, que puede emitir / recibir datos en divisiones de tiempo, donde un primer sistema realiza las siguientes etapas: (a) detección de si uno o varios otros sistemas activos se encuentran en el alcance de recepción / emisión, y (b) detección (3) de los desplazamientos de tiempo relativos de las divisiones de tiempo de cada uno de los otros sistemas activos en el alcance de emisión / recepción con respecto a las divisiones de tiempo del primer sistema, (c) memorización (4) de los desplazamientos de tiempo relativos detectados, y (d) modificación (5) de la posición temporal de las divisiones de tiempo del primer sistema a través de una elevación o reducción de una frecuencia básica del primer sistema.
