Abstract :
Partial transmit sequences (PTS) and Pulse shaping (PS) are two effective techniques for reducing the peak to average power ratio (PAPR) of OFDM system. The main disadvantage of PS method is spectrum loss, and PTS has high computation complexity. A new combined technique of PS and PTS is proposed in this paper. The simulation results show that the proposed concatenated technique achieved a better performance on reducing PAPR of OFDM system while inhibiting the main drawbacks of each original method.
