With the rapid growth of digital wireless communication in recent years, the need for high speed mobile data transmission has increased. New modulation techniques are being implemented to keep up with the desired more communication capacity. Processing power has increased to a point where OFDM has become feasible and economical. Some examples of current applications using OFDM include DVB (Digital Video Broadcasting), DAB (Digital Audio Broadcasting), and HDTV (High - Definition TeleVision). OFDM as a transmission technique has been known having a lot of strengths compared to any other transmission technique, such as its high spectral efficiency, its robustness to the channel fading.
