OFDM PAPR reduction using clipping with distortion control

We propose a new PAPR reduction scheme for OFDM systems. The idea is to reduce PAPR and control clipping distortion simultaneously. The procedure includes setting a proper distortion bound and recursive operations of clipping, filtering and distortion control. The proposed scheme can achieve significant PAPR reduction while maintaining low error rate. For this scheme, PAPR reduction is obtained without any redundancy and no side information is needed in the OFDM receiver. Hence, OFDM systems using this scheme do not pay the price of the reduction of transmission rate or reliability for achieving PAPR reduction.
