Abstract

This paper proposes an adaptive soft clipping method for spectrum sharing OFDMA systems. The proposed method controls in-band and out-of-band distortion power by changing the nonlinearity parameter of soft clipping. The simulation results show that the proposed method can control the distortion power by 10 dB for a practical power amplifier. The results also show that a low-peak OFDMA transmitter can be realize with reasonable computational complexity because iterative processing for peak power reduction is unnecessary.
