无线能量采集正在成为无线网络能量采集的关键技术之一。另一方面，干扰对齐(IA)是无线网络中一种很有前途的干扰管理解决方案。虽然在WeH和IA方面已经做了大量的工作，但在现有的大多数文献中，这两个重要领域都是分开讨论的。在本文中，我们对智能网中的WH进行了概述，并提出了一个联合研究WH和IA的统一框架。为了同时优化IA网络的信息传输性能和WH性能，提出了一种功率分裂优化(PSO)算法。此外，本文还对粒子群算法中的功率分配问题进行了研究。给出了仿真结果，比较了提出的WH方案在IA网络中的性能。还提出了IA网络中WH的一些有趣的研究挑战。
Wireless energy harvesting (WEH) is becoming one of the key techniques in energy harvesting in wireless networks. On the other hand, interference alignment (IA) is a promising solution for interference management in wireless networks. Although plenty of effort has been conducted on WEH and IA, these two important areas have been addressed separately in most of the existing literature. In this article we provide an overview of WEH in IA networks, and present a unified framework to jointly study WEH and IA. To simultaneously optimize both information transmission (IT) and WEH performance in IA networks, we propose a power splitting optimization (PSO) algorithm. In addition, we study the power allocation problem in the proposed PSO algorithm. Simulation results are presented to compare the performance of the proposed schemes for WEH in IA networks. Some interesting research challenges are also presented for the WEH in IA networks.
