| 摘 要： | 较大的峰均功率比限制了OFDM技术的广泛应用,如何选择复杂度低而且抑制效果良好的高峰均比算法是目前这一领域研究的重点。本文利用选择性映射方法和限幅方法在性能上的互补性,提出了一种映射和限幅的联合算法（SLM-Clipping联合算法）。仿真结果表明,该方法有效的降低了OFDM系统的峰均比,而且具有复杂度低,易实现等优点。

| Abstract: | The wide application of the orthogonal frequency division multiplexing （OFDM） is restricted due to the high peak-toaverage power ratio. How to select an easy-implement and efficient algorithm is the focus of this area. By making the use of the complementary character between the SLM and clipping algorithms, this paper produces a new algorithm which combines the two algorithms. Simulation results show that the proposed method can reduce the PAPR with low complexity and easy to achieve. |
