With the recent growth of wireless communications and the increasing demand for high transmission rates, Orthogonal Frequency Division Multiplexing (OFDM) is being considered the desirable modulation scheme of most future wireless communication technologies. Many wireless standards have already rallied in favor of OFDM. The attractive features of OFDM are numerous; a key advantage over other classical modulation schemes is that OFDM can be designed to reach a high spectral efficiency. The main advantage in practice lies in the flat fading aspect of the channel that facilitates equalization at the receiver side.
