A PAPR reduction method based on the selection scheme of Zadoff-Chu matrix and SCAFBD

OFDM is widely used in communication systems for its advantages such as high spectral efficiency and anti-multipath effect. However, the drawback of high PAPR greatly limits its own development. Many techniques have been proposed to reduce PAPR, but none of them is widely used because of the poor performance and complexity. The proposed method exploits a selection scheme based on Zadoff-Chu matrix and SCAFBD(simplified clipping And Filtering with bounded distortion). In order to maximize the reduction of PAPR, the proposed method is the one in line with the minimum PAPR of the largest PAPRs per frame generated by Zadoff-Chu matrix and SCAFBD according to their characteristics. Simulation results show that the proposed scheme achieves quite good performance.
