Abstract

In this paper, we investigate the performance of offset quadrature amplitude modulation based orthogonal frequency division multiplexing (OQAM-OFDM) systems using an adjacent channel leakage power ratio (ACLR) and error vector magnitude (EVM) restricted peak amplitude cancellation scheme for peak-to-average power ratio (PAPR) reduction, where peak amplitude of the transmit signal that exceeds a give threshold level is iteratively suppressed by adding a peak cancellation (PC) signal which exhibits sharp peak amplitude at the midpoint of pulse waveform in time domain. In addition, using this scheme, both ACLR and EVM are automatically adjusted so as to meet a given requirement. In the proposed scheme, both PAPR reduction performance and system requirements such as out-of-band spectrum radiation and in-band distortion are simultaneously taken into consideration. Through computer simulation results, it is demonstrated that the proposed PAPR reduction scheme is effective in reducing PAPR of pulse shaped OQAM-OFDM signals, while both ACLR and EVM requirements are simultaneously fulfilled.
