Stealth Evaluation of the OFDM Communication System

The necessity of increase the stealth of the digital radio communication systems is showed in the paper. Functional principles, advantages and application fields of communication systems with OFDM modulation are reviewed. The possibilities of using application of signals with OFDM modulation in the stealthy command radio network is also analyzed. For this purpose, simulated the “shape” of the OFDM-signal in pseudo-phase space and visually evaluated that its structure is close to regular processes. The stealth of the systems with OFDM-modulation using BDS-statistic in comparison with “white” noise is estimated. The ways to increase the stealth of OFDM signals by using chaotic processes and sequences are proposed. At the summary are defined the directions of further researches.
