A new chaotic attractor from Rucklidge system and its application in secured communication using OFDM

Attractors over OFDM is an emerging research concept which has immense potential for secured communication. The dynamic behavior of Rucklidge system leads to various strange attractors according to varying initial conditions and parameters. In our work one such new strange attractor has been developed and transmitted through OFDM and its behavior has been studied using MATLAB simulation. The performance of the system has been analyzed using BER vs E

graph when the modulation schemes done with QPSK, 16-QAM and 64-QAM. It was observed that its security level has been enhanced because of the monovular nature of decoding it by using the same initial conditions as that of given at formation of strange attractor from the Rucklidge system.
