As one of the most attractive techniques, partial transmit sequence (PTS) provides an effective solution for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems, however, results in large computational complexity simultaneously. Compared to PTS, clipping provides a simpler way towards a better PAPR performance, whereas results in degradation of the bit error rate (BER) performance. In this paper, we proposed two joint algorithms called quantization clipping (QC) and recoverable clipping (RC), which combined PTS with modified Clipping schemes. The proposed schemes achieve a better exploitation of advantages, simulation results show that the proposed joint algorithms do not only significantly improve the PAPR reduction performance but also achieve a non-loss BER performance.
