Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against multipath fading. However OFDM signals have a problem with high Peak-to-Average Power Ratio (PAPR) and thus, a power amplifier must be carefully manufactured to have a linear input-output characteristic or to have a large input power back-off. The drawbacks of high PAPR can outweigh all the potential benefits of Orthogonal Frequency Division Multiplexing (OFDM) signals.
