摘要
介绍了降低OFDM系统PAPR的PTS算法,提出了将PTS算法进行限幅处理的一种方法。通过仿真,表明算法在保持原算法优点的基础上,有效降低了OFDM信号PAPR值,并对系统性能影响不大。
In this paper, we introduced a PTS algorithm of reducing OFDM peak to average power ratio, and found a way of reducing the ratio. Through emulating, we found out the algorithm kept the advantages of original algorithm, reduced the PAPR value of OFDM signal, and had little effect on system performance.
