Abstract

Method of digital information transmission against the background of voice signals for analog VHF radio channels of maritime and air mobile radiocommunication services is designed. The method is based on principles of digital steganography and digital watermarking technology. Experiments were conducted in the real VHF radio channel with signal processing in Matlab environment. Bit rate of 40 bit/s is achieved in 300÷3000 Hz frequency band with channel signal-to-noise ratio 20 dB.
