Abstract

The kinetics of higher data requirements in the upcoming wireless generation is engendered by the fact that the usage of high quality multimedia applications in the form of data, audio, SMS and video is on the rise. In order to meet the challenging needs of the increasing data rate requirements, the wireless system employs Orthogonal Frequency Division Multiplexing (OFDM). Security is the need of the hour in today’s wireless technological advancement. In this study, OFDM with Reed Solomon codes (RS) as Forward Error correction codes (FEC) has been proposed to achieve lower Bit Error Rate (BER) and data embedding has been carried out to ensure security in wireless communication. Further RS codes are used to restore the cover object.
