Abstract
Un sistema y un método para establecer una sincronizacion inicial para el enlace entre un UE y una estacion base en una red de comunicacion utilizan logica de exclusion de ventana para evitar un estado de interbloqueo ante una deteccion de la red terrestre movil publica (PLMN) equivocada. La senal de comunicacion es procesada en un procedimiento de decision de tres pasos. El primer paso de decision determina un desplazamiento de chip de la vía más intensa detectada en un cuadro de muestras. Como respuesta a la primera decision, el segundo paso genera un numero de grupo de codigo de mezclado y un desplazamiento de ranura para recuperar el secundario codigo de sincronizacion. El tercer paso de decision recupera un codigo de mezclado primario como respuesta al numero de grupo de codigo para sincronizar el UE a la estacion base.
