摘要
Abstract
The digital multi-layer corridors required for Urban Air Mobility(UAM)operations exhibit inherent dynamic characteristics.Consequently,the coverage of Low-Altitude Wireless Networks(LAWN)must possess timely adjustment response capabilities,making large-scale phased array-based multi-beamforming a potential solution.Multi-beamforming for multi-layer corridors faces dual challenges:i)dynamic changes in corridor coverage requirements and inter-beam overlap caused by nonlinear mapping in the angular domain during multi-beam plan-ning;ii)element output distortion induced by high transmission power for long-distance links,which alters the array radiation pattern.This paper analyzes the impact of array deployment on the angular domain projections of multi-corridors and proposes a coverage deployment scheme tai-lored for multi-corridor templates to enhance communication coverage.Furthermore,incorporating the effects of element nonlinear distortion,a multi-beamforming scheme is proposed to maximize the system average transmission rate.Simulation results demonstrate that the proposed scheme can achieve a maximum throughput improvement of 21.6%without increasing the number of array elements.关键词
