Cyclostationary signature suppression in chaos-based communication system

It has been shown that some chaotic signals have second-order cyclostationary characteristics. Since the cyclostationary properties of the transmitted chaotic signal can be easily detected by an enemy, this paper focuses on the suppression of cyclostationary properties present in chaotic signals. We introduce a new method based on the time symbol randomization to eliminate the spectral lines corresponding to the multiples of the baud rates. Finally, we compare our proposed method to another existing method to show the efficiency of our approach to eliminates the cyclostationary properties.
