摘要

分布式波束形成是无线网络中节点之间的一种合作形式,以有效地将公共消息传递给远程接收器。实现电磁相干性的关键要求是同步所有本地振荡器的初始相位,引入最小的开销和复杂性。本文介绍了随机、确定性和混合算法,它们都是基于普通接收机的反馈作为驱动力,但采用了不同的相位更新策略。数值结果表明,这些算法比以往提出的方法收敛速度更快。

Random, deterministic, and hybrid algorithms for distributed beamforming
Distributed beamforming is a form of cooperation among nodes in a wireless network to efficiently deliver a common message to a distant receiver. The critical requirement to achieve electromagnetic coherence is to synchronize the initial phases of all local oscillators, introducing minimal overhead and complexity. In the paper we introduce random, deterministic and hybrid algorithms, all based on feedback from the common receiver as the driving force, but with different phase update strategies. Our numerical results show that these algorithms achieve faster convergence time than previously proposed approaches.
