摘要
由于星地链路与地面传播损耗特性之间的差异，卫星通信系统的频谱效率指标远低于同期的地面蜂窝系统。多波束天线技术能够实现更高效的空分复用，是提升低轨卫星通信系统频谱效率的重要手段。研究低轨卫星通信场景下的自适应波束成形及多普勒频移补偿方案。首先，基于混合波束成形架构设计一种低复杂度的波束成形方案；其次，针对多波束系统中由不同波束俯仰角带来的多普勒频移差异，提出一种多波束系统中的多普勒频移预补偿方案；最后，通过MATLAB仿真分析验证算法的有效性。
Abstract
Because of the difference between satellite-ground link and ground propagation loss characteristics
the spectrum effi ciency index of satellite communication system is far lower than that of terrestrial cellular system in the same period.It is of utility to improve spectral effi ciency by realizing effi cient space division multiplexing with multi-beam antennas.The adaptive beamforming and doppler frequency off set compensation scheme in the LEO multi-beam satellite communication scenario was studied.Firstly
a low-complexity hybrid beamforming scheme was designed.Then
aim at the doppler frequency shifts were diff erent between beams due to their pitch angles
a doppler frequency off set pre-compensation scheme for multi-beam systems was proposed.Finally
the eff ectiveness of the algorithm was verifi ed by MATLAB simulation analysis.
