An Improved Serial Peak Cancellation Method for PAPR Suppression in OFDM System

doi:10.3969/j.issn.1000-1093.2020.03.013

Abstract

Abstract: An improved serial PAPR suppression method is proposed for the high peak-to-average power ratio（PAPR） of orthogonal frequency division multiplexing（OFDM）system. The proposed method is used to find the peak point exceeding the threshold via the rising edge and falling edge of signal amplitude. In the proposed method, a weighted window is used to effectively suppress the high peak in a serial processing mode. Simulated results show that, compared to the existing methods, the improved method is capable of effectively suppressing the PAPR, while the number of peak cancellations is reduced by its accurate peak search, which helps to reduce the implementation complexity and enhance the bit error rate (BER) performance.
