Abstract

To reduce the PAPR (Peak-to-Average Power Ratio) in the Filtered-OFDM (F-OFDM) system, we propose an amplitude clipping method working together with the subband filter in the F-OFDM system. Firstly, a power level is preset to clip the real and imaginary parts of F-OFDM signals for reducing the peak energy of transmitted signals. Then the spectrum leakage and distortion caused by amplitude clipping are mitigated by the designed subband filter of F-OFDM system. The simulation results demonstrate that such a combined method can suppress PAPR effectively and maintains good BER (Bit Error Rate) performance compared with the traditional OFDM system.
