Combination sine PS method for PAPR reduction in OFDM systems

The pulse shaping (PS) is an effective and flexible technique for reducing the peak to average power ratio(PAPR) of orthogonal frequency division multiplexing (OFDM) system. However, different PS waveforms result in different probabilities of reducing the PAPR of OFDM signals. A combination sine pulse shaping (CS-PS) technique is proposed in this paper. The CS-PS waveform contains a linear term and three sine terms. Simulation results show that the CS-PS can get better performance of reducing the PAPR compared to conventional PS method.
