Improved Signal to Noise Ratio (SNR) and variable higher data rates will pave a way to a brighter future for the next generation broadband applications of wireless communication. The OFDM system tolerates robustness against the multipath effects encountered by the fading channels. Enhanced system is achieved by using Forward Error Correction (FEC) codes. The attrition of errors in signals will increase the reliability of the system. In this study, secret data has been embedded after encoding the data using Convolutional encoders and passed over OFDM system. At the receiver end, Artificial Neural Network (ANN) helps better BER. The signals are passed over an OFDM receiver and decoded using Viterbi decoders.
