Orthogonal Frequency Division Multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. It is one of the modulation techniques which are multi-carrier, gives a high spectral efficiency, immunity to the frequency selective fading channels, power efficiency and multipath delay spread tolerance. It is more advantageous over other technologies. Although its advantages it has some obstacle also. The high peak-to-average ratio is the main obstacle which causes non-linearity at the receiving end. One of the major disadvantages in OFDM communication is the high Peak-to-Average Power Ratio (PAPR).
