Padmapriya Praveenkumar, K. Thenmozhi, J.B.B. Rayappan and Rengarajan Amirtharajan

Abstract: The prospects of the next generation wireless broadband applications will be enhanced by the features like improved Signal to Noise Ratio (SNR) and variable higher data rates. The Orthogonal Frequency Division Multiplexing (OFDM) system offers better tolerance against multipath effects faced by fading channels. Forward Error Correction (FEC) codes meliorate the system performance. In this study, firstly the data is encoded using Convolution encoders with Puncture codes in OFDM system. Then, the secret message is embedded and passed through Rayleigh and Rician fading channels. The BER graph prior and after embedding the confidential data are compared and simulated using BPSK modulation scheme. The system is made more reliable by reducing the redundancy, errors in the signals and making it more secure and robust in fading environment.
