In recent years, multimedia based application which requires the technology that supports high speed data transmission is growing rapidly. To achieve this high speed communication Orthogonal Frequency Division Multiplexing (OFDM) is most widely used technology. OFDM system makes the use of orthogonal subcarriers for data transmission with efficient usage of available bandwidth. However as number of subcarriers goes on increasing, Peak to Average Power Ratio (PAPR) of OFDM signal also increasing. This high PAPR causes significant distortions when passed through non-linear amplifier.
