Orthogonal Frequency Division Multiplexing (OFDM) is the most promising modulation technique. It has been adopted by most wireless and wired communication standards. The idea is to utilize a number of carriers, spread regularly over a frequency band, in such a way so that the available bandwidth is utilized to maximal efficiency. This paper is to carry out an efficient implementation of the OFDM system (i.e. transmitter and receiver) using different encryption and compression algorithm for the energy optimization on data transmission.
