Abstract
Reducing the peak-to-average power ratio (PAPR) of Orthogonal frequency division multiplexing (OFDM) has become the most popular technology for high data rate transmission in recent years. However, most of the proposed schemes either have a high computational complexity or poor bit error rate (BER) performance. Among them, signal clipping is the simplest method to improve the OFDM system's PAPR performance, but it results in serious degradation of the BER performance. In this paper, a modified Clipping scheme based on quantization method is proposed by quantizing the transmitted signal to a group of preset threshold. Simulation results show that the new scheme can significantly improve the BER and the out-of-band radiation performance while guaranteeing the PAPR performance of the QAM-OFDM system. © 2013 Springer International Publishing.
