摘要 提出了一种基于星座映射选择改善正交频分复用(OFDM)信号峰值平均功率比(PAPR)的方案,并针对这种映射方案提出了一种基于格栅搜索的简化算法。仿真表明,该方法不仅能够有效降低OFDM系统的峰均功率比,并具有较低的复杂度和较好的实用价值。 An agorithm for rducing the Peak to Average Power Ratio （PAPR） of OFDM signal based on constellation mapping is presented, and a low complexity search algorithm using trellis factor search is proposed for the method. Computer simulation shows that the proposed scheme is not only effective in reducing the PAPR, but also with low complexity and good practical value.
