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.Keywords

Resources are inevitable to every nation for its sustainable growth. These resources contribute to the application of available energy into use. Among various energy sources, solar energy has the capacity of expanding into large scale operations and fulfils the industrial and domestic purpose. Now-a-days, solar energy has its utilisation in many ways. Due to low level of commercial competitiveness, solar energy has a slow growth in developing countries. Moreover, the consumers are not well aware of the importance of solar energy products and their usage. In order to enhance the usage of solar energy products, promotional activities have to be driven actively. Buying behaviour and issues relating to social attitude generates great barrier in promoting them. Advertising serves as an effective tool in the marketing machinery to promote solar energy products. There is also demand for promoting awareness and enhancing commercial competitiveness on solar energy. In this regard, the present study analyses the level of opinion and agreement towards enhancing promotional activities for utilisation of solar energy products and the reasons for not buying solar energy products. Convenience sampling technique has been adopted to select the respondents and the sample size is 110. Simple Percentage Analysis, Chi-square test and Weighted Average Ranking Score analysis have been used for analysis. The study found that majority of the respondents highly agrees that promotional activities will enhance the utilisation of solar energy products. Further, the study revealed that there is a significant association between gender, occupational status, marital status, family type, family size and level of agreement towards promotional activities to enhance utilisation of solar energy products in Erode District. The main reason for not buying the solar energy products is found to be lack of awareness. It is emphasized that advertisement is an effective tool to promote solar energy products.Keywords
