Abstract: In the era of wireless communication, the World Wide Web is
the brain child of all the new technological development. This digital world
has speeded up the data transfer and communication speed a manifold, creating
new goods and services all along. Along with the development of internet, developed
ways of hacking, modifying and stealing it also increased. There is an increasing
demand to augment the data rates and to provide greater fidelity. Thus, technology
provides us the finesse for increasing robustness over fading channels. The
most prominent solution for increased speed is OFDM. And the security issues
can be taken care of by embedding confidential data after encoding the message
using cyclic codes.
