Information Scrambling by Lorenz System Based Sequences in OFDM

Abstract

This paper presents the modeling results OFDM system with use chaotic scrambling of signal constellation. In this paper statistical characteristics, the bit error rate (BER) and Peak to Average Power Ratio the signals in the system are estimated. The correlation coefficient between adjacent pairs of chaotic permutation vectors as a assessing the ability to withstand a statistical attack is estimated. The scrambling degree (SD) is evaluated. The results can be used in the design of modern communication systems in order to increase the security of transmitted information.
