Abstract

Taking into account the rising interest to use the chaotic signals in information transmission systems raises the question of how they can be success disclose by means of radio intelligence. The paper considers the method of evaluation of the chaotic signals with OFDM-modulation using nonparametric BDS-statistic. It was demonstrated that based on the differences in topological features in “shapes” in pseudophase space of a chaotic, regular, and random process can be solved the task of evaluating the parameters of chaotic signals to its observation in “white” noise. The results of numerical estimation of the proposed method in relation to the level of noise were showed.
