Practical realization of the chaotic carrier generator provided on the basis of the signal processor, digital-to - analogue converter and the clock pulse oscillator is offered in the work. The algorithm of formation of chaotic sequence on the basis of a programming environment C++ is synthesized. Shows a functional diagram of the experimental setup forming chaotic carrier that allows leading the digital chaotic sequence generated using a signal processor to analogue. It is shown that the resulting time series of chaotic carrier is similar to the noise of observation (white noise). It provides the possibility of using such a chaotic carrier to enhance the secrecy operation of radio systems.
Keywords: generator of chaotic carrier’s experimental setup, Nyquist theorem, noise monitoring, secrecy
