Abstract
Orthogonal frequency division multiplexing (OFDM) has the advantages of spectral efficiency in wideband communication systems such as 3GPP long-term evolution (LTE). However, OFDM suffers from a high peak-to-average power ratio (PAPR). Several schemes, such as peak windowing, clipping and filtering, have been proposed in order to reduce the PAPR in OFDM-based systems. However, these schemes reduce the peak signals regardless of the PAPR pattern; thus, while guaranteeing error vector magnitude (EVM) and adjacent channel leakage ratio (ACLR) performances they do not efficiently reduce the PAPR. In this paper, we propose a hybrid peak-windowing scheme that selects the optimum PAPR reduction scheme according to the PAPR pattern, and we evaluate its performance using a real LTE test bed. Our test results show that the proposed scheme outperforms the existing schemes in terms of EVM, ACLR, and power consumption.
