摘要:

本文提出了一种适用于基于解码转发的协作无线信息功率同步传输网络的动态功率分配方案。中继节点采用由瞬时信道状态信息(CSI)确定的最优动态功率分配因子来获取能量和处理信息。推导了该网络的最优动态功率分配因子、中断概率和各态历经容量的表达式。数值结果表明,该方案在中断概率方面优于或等于现有的PS方案,而与现有的PS方案相比,它实现了更高的遍历容量。

英文摘要:

This letter proposes a dynamic power splitting scheme (DPSS) for decode-and-forward (DF) based cooperative simultaneous wireless information and power transfer (SWIPT) networks with direct link. The relay node adopts an optimal dynamic power splitting factor determined by instantaneous channel state information (CSI) to harvest energy and process information. The expressions for the optimal dynamic power splitting factor, outage probability and ergodic capacity of the proposed network are derived. Numerical results show that the proposed scheme is better than or the same as the existing PS schemes in terms of outage probability, while it achieves higher ergodic capacity compared to the existing PS schemes.
