In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mapped to the constellation points such that the MSBs are less affected by the channel errorthan the LSBs. In the proposed method, the MSBs are changed by an intentional error such that the PAPR is minimized. The performance of this method has been presented and it has been shown that it achieves the better performance than that of the Selected Mapping (SLM) method.
