标题： Pinching Antenna-Aided Wireless Powered Communication Networks

摘要： 在本文中，我们研究了一种新型夹紧天线（PA）辅助的无线供电通信网络（WPCN），其中多个PA沿波导激活，以与多个设备建立稳健的视距链路。 在PA-WPCN中考虑了时分多址（TDMA）和非正交多址（NOMA）协议。 此外，一些实际考虑因素，包括PA的成比例功率模型、波导传输损耗模型和非线性能量收集模型，都被纳入PA-WPCN中。 此外，我们通过联合优化资源分配和PA的位置来制定一个总速率最大化问题。 为了解决PA位置优化的挑战性问题，我们提出了一种高性能的逐元素（EW）算法和一种低复杂度的随机参数差分进化（SPDE）算法。 数值结果验证了所提出的PA-WPCN的显著性能和我们算法的有效性，表明当PA功率分配比约为0.55-0.6时可以获得最佳性能。 显示英文摘要

摘要： In this letter, we investigate a novel pinching antenna (PA)-aided wireless powered communication network (WPCN), in which multiple PAs are activated along a waveguide to establish robust line-of-sight links with multiple devices. Both time division multiple access (TDMA) and non-orthogonal multiple access (NOMA) protocols are considered in the PA-WPCN. Moreover, some practical considerations, including a proportional power model for the PAs, a waveguide transmission loss model, and a nonlinear energy harvesting model, are incorporated into the PA-WPCN. Furthermore, we formulate a sum-rate maximization problem by jointly optimizing resource allocation and PAs position. To address the challenging problem of the PAs position optimization, we propose a high-performance element-wise (EW) algorithm and a low-complexity stochastic parameter differential evolution (SPDE) algorithm. Numerical results validate the remarkable performance of the proposed PA-WPCN and the effectiveness of our algorithms, indicating that optimal performance is attained when the PA power distribution ratio of approximately 0.55-0.6.
