Rayleigh-Benard Attractor for OFDM


  • Department of Electronics and Communication Engineering, School of Electrical and Electronics Engineering, SASTRA University, Thanjavur - 613401, Tamil Nadu, India


Objectives: Emerging trends in non-linearity has resulted in “Strange Attractors” which is highly chaotic in nature. In this paper the strange attractor – chaotic signal is being applied on the Orthogonal Frequency Divisional Multiplexing (OFDM) system and its performance is measured. Methods/Statistical Analysis: The work is divided into two parts– generation of the strange attractor, application of the attractor on the OFDM System. After generating strange attractor from Rayleigh-Bernard System, it is utilized by OFDM with different modulation techniques such as 16-QAM, 64-QAM and QPSK. A chaotic signal in OFDM transmission is seems to be rare combination for secured communication and that gains the novelty in this paper by applying strange attractors to OFDM technique. Findings: Performance of the Rayleigh Bernard Attractor with OFDM system has been estimated with BER vs Eb/N0 plot and its security has been verified by calculating password decoding time. Application/Improvements: Rayleigh Bernard Attractor for OFDM system helps in the secured transmission and reception of the signal.
