摘　　要：本文提出了一种新的部分传输序列(PTS)方法,该方法利用交织分割的周期性,传输较少的边带信息,提高了频谱利用率,恢复信号时不会增加计算复杂度也不会提高系统的误码率。通过逐步缩小最优解范围的搜索方式,把传统PTS方法需要的指数级计算量的缩减到乘数级,经过仿真模拟,所提出的PTS方案的性能几乎不回下降。In this paper,a new partial transmission sequence(PTS)method is proposed.This method uses the periodicity of interleaving and segmentation to transmit less sideband information,improves the spectrum utilization,and does not increase the computational complexity or restore the signal.Improve the bit error rate of the system.The search method that gradually narrows the optimal solution range reduces the exponential calculation required by the traditional PTS method to a multiplier level.After simulation,the performance of the proposed PTS scheme hardly drops back.
