In modern world of communication systems, various new methods have developed to replace the previous conventional techniques that provide data communication with high speed. As wireless communication guidelines were developed it became necessary to develop new techniques like Orthogonal Frequency Division Multiplexing (OFDM) for data security and reliability while data transmission. Idea behind the high spectral efficiency of OFDM is elimination of guard bands and use of the overlapping but orthogonal subcarriers. The communication process to optimize the energy consumption level on the original transmission input signal level and the signal process is to effectively improve the wireless communication applications.
