The first information data stream is transmitted over the data subcarriers in parallel to the CAZAC sequence over the guard band subcarriers.

Abstract: A method for disinfecting a vehicle drinking water tank is designed for dynamic disinfection. By providing a vehicle drinking water tank with a spray diffuser, which is arranged inside the vehicle drinking water tank, the disinfecting liquid can be sprayed over substantially the entire inner surface of the tank. Partial filling of the drinking water tank with a disinfecting liquid starts the disinfection method. The dynamics of the disinfection method are achieved by spraying the disinfecting liquid in such a way that a moved film of disinfecting liquid is formed and wets an inner surface of the drinking water tank. Material transport at the inner wall of the tank is improved and mechanical shear forces act on the biofilm, which is to be removed and/or disinfected, in combination with the biochemical disinfection forces.
