Abstract
A main drawback of OFDM systems is the high peak-to-average Power Ratio (PAPR) which can result in significant distortion when transmitted through power amplifiers. The conventional peak cancellation method (cPCM) is widely used in PAPR reduction, but for OFDM signals, the cPCM is of high complexity. In this paper, a simplified peak cancellation method (sPCM) is proposed for OFDM signals, which obtains a low computational complexity and equivalent performance in PAPR reduction.
