摘要：
Orthogonal frequency division multiplexing with offset Quadrature amplitude modulation technique has drawn significant interest in recent years. However, most of the existing Peak-to-Average Ratio (PAPR) reduction schemes cannot be used in the OFDM/OQAM system directly. In this paper, a modified scheme called overlapped segmental approach is implemented with Deep-clipping (DC), Heavy side-Clipping (HC), Classical-Clipping (CC) and Smooth-Clipping (SC) for reducing the PAPR problem specifically in the OFDM/OQAM system. The effectiveness of these techniques are analysed in terms of PAPR-reduction, and Bit Error Rate (BER) degradation. From the analysis and simulation results, Deep Clipping method seems to be the best of the four methods, because of its flexibility in PAPR reduction and BER.
