摘要

战术空对地通道对物理层波形设计提出了许多挑战,包括:(i)机载平台动力学(即多普勒、频率偏移、跳变等),(ii)从良性到严重的地面多径,以及(iii)部分到完全阻挡视线(LOS)路径。传统的军用波形在提供现代战术通信所需的数据速率的同时,在这些恶劣的信道中不能有效地运行。

On the design of a modern broadband communications waveform for tactical air-to-ground links
Tactical air-to-ground channels present a number of challenges for physical (PHY) layer waveform design including: (i) airborne platform dynamics (i.e., Doppler, frequency offset, jerk, etc.), (ii) benign to severe ground-level multipath, and (iii) partial to full blockage of the line-of-sight (LOS) path. Legacy military waveforms are not sufficiently robust to operate effectively in these severe channels while providing the data rates required for modern tactical communications.
