Radio transmission masking on the example of FSK modulation
E. Szczepaniak, Zbigniew Piotrowski · 2017
The paper outlines methods that employ the properties of popular FSK (Frequency-shift Keying) modulation for covert transmission of data between two radio transceivers. With the use of dedicated modulation, the risk of interception of confidential information on military radio channels is considerably reduced. The paper also discusses the methods of radio signal modulation in practical applications, providing detailed mathematical description thereof. Also, the results of test performed on dedicated laboratory station were provided.
