The paper was developed a method for increasing stealth transmission of digital information in a wireless communication system that is based on the use of chaotic signals (processes) for MSK-harmonic modulation of the carrier. The block diagram of a receiver and a transmitter is shown. The analysis of the quality of the information message recovery by calculating the probability (rate) of bit errors are commensurate with the same coefficients obtained for binary data transmission systems using as a carrier harmonics. The estimation of the gain in increasing secrecy of the information signal (using the BDS-statistic). It is shown that this method of communication increases the stealth operation of radio systems due to the similarity of statistical and dynamic characteristics of an information signal with similar observation noise (white noise).
