| 摘 要： | 高峰均功率比（PAPR）信号是正交频分复用（OFDM）技术实用化过程中必须加以考虑与解决的问题,针对该问题,研究了降低PAPR的部分传输序列算法以及多种改进算法,基于系统计算复杂度的考虑,本文在迭代搜索的次优PTS算法基础上提出一种基于子块联合分割的新算法。仿真结果证明,所提算法保持了良好的PAPR降低性能,并有效的降低了计算的复杂度,是一种比较实用的算法。

| Abstract: | The high Peak-to-Average Power Ratio must be taken into account and resolved in putting OFDM system into practice. Aiming at the problem, PTS algorithm and its improved algorithms are well studied. With consideration of the computational complexity, a novel algorithm based on combined sub-block division of the iterative searching algorithm is proposed. The simulation results show that the proposed algorithm is practicable and could achieve good PAPR reduction and low computational complexity. |
