Analysis
This paper addresses the problem of optimizing antenna positioning and beamforming in pinching-antenna systems, which are designed to mitigate signal attenuation in wireless networks. The research focuses on a multi-user environment with probabilistic line-of-sight blockage, a realistic scenario. The authors formulate a power minimization problem and provide solutions for both single and multi-PA systems, including closed-form beamforming structures and an efficient algorithm. The paper's significance lies in its potential to improve power efficiency in wireless communication, particularly in challenging environments.
