A system and method for carrying out a hand-off of a satellite-based communications link with a mobile platform, such as an aircraft, leaving a first coverage region and entering a second coverage region. The paper sheet processing device is configured to process paper sheets. The mixed oxides contain zirconium oxide and hafnium oxide mixed with one or more oxides of yttrium, scandium, lanthanide elements, and optionally mixed with one or more of SiO2, Na2O, and TiO2. The filtering process of the noise reduction system is controlled by both global and local image statistics that are also computed by the system.
