摘要

物理层网络编码(PNC)是无线通信网络中网络编码的自然延伸。PNC合理地利用了电磁波的附加特性，显著提高了无线网络的通达性。本文重点研究了PNC中的一个关键问题:脉冲整形对时间同步误差性能的影响。分析和仿真结果表明，采用无ISI的脉冲整形时，滚转系数为零的升余弦脉冲能最大程度地抵抗PNC中时间同步误差带来的功率损失。采用高斯脉冲整形时，以1为参数对PNC中由于时间同步误差引起的功率惩罚效果最好。

The effect of pulse shaping on the performance of physical-layer network coding with time synchronization errors

Physical-layer network coding (PNC) is a natural extension of network coding in wireless communication networks. PNC utilizes the addition characteristic of the electromagnetic wave rationally and improves the throughout in wireless networks significantly. This paper focuses on a key issue in PNC: the effect of pulse shaping on the performance of time synchronization errors. Analysis and simulation results show that raised cosine pulse with roll-off coefficient of zero can resist power penalty furthest due to time synchronization errors in PNC when adopting pulse shaping without ISI. Also when adopting Gaussian pulse shaping, we can get the best effect with parameter of one on resisting power penalty due to time synchronization errors in PNC.
