摘要
提出一种联合PS与PTS的新技术,结合了两者的优点,在抑制OFDM系统PAPR的性能上表现更好。仿真结果证明,在相同频带利用率条件下,联合法比PS技术的抑制PAPR能力更强,在抑制OFDM系统PAPR性能和降低计算复杂度的同时,频带利用率基本保持不变。
In this paper, a new technique combined of PS and PTS is proposed. While avoiding PS and PTS＇s defects, the combined technique takes advantages of them and has a better performance on inhibiting PAPR of OFDM system. The simulation results show that the joint-technique has more performance on inhibiting high PAPR than PS with the same bandwidth efficiency, compared with PTS, the complexity of algorithm is reduced and the inhibition of OFDM system＇s PAPR is enhanced, it still has basically the same bandwidth efficiency.
