DESCRIZIONE
- Transmission of the communication data by means of the first radio communication system from at least one first transmission unit to at least one first reception unit, one or more first transmission frequencies being assigned to the first radio communication system, and transmission of at least one pilot symbol by means of a second radio communication system different from the first radio communication system from a second transmission unit to at least one second receiving unit, the second radio communication system being assigned one or more second transmission frequencies that are different from the first transmission frequencies of the first communication system, - the pilot symbol being transmitted within the coherence bandwidth of the communication data, - Carrying out a channel estimation of the transmission channel as a function of the received pilot symbol by means of an evaluation unit to support the decoding function.
