<p>In this work, we propose a novel method to mitigate clipping noise in OFDM systems. Unlike conventional techniques, our approach does not alter the signal’s peak to average power ratio (PAPR); instead, it increases the power amplifier output back-off (OBO) and suppresses clipping noise by applying a scaling factor that reduces the magnitude of the modulated symbols. Although this strategy inherently reduces the signal-to-noise ratio (SNR), we carefully optimize the scaling factor to balance the reduction of clipping distortion with the preservation of SNR. Compared to the conventional method that relies solely on power amplifier back-off, our approach delivers superior bit error rate (BER) performance. Moreover, it is also spectrally efficient, requiring no additional parameter transmission over the wireless channel if constant-envelope modulation schemes are used. Our approach also offers significantly reduced computational complexity when constant-envelope modulation schemes are employed, and maintains comparable complexity to that of the conventional method for other modulation types. Simulation results demonstrate that the proposed method performs particularly well under high SNR conditions.</p>
