高速运动环境TDMA卫星通信同步控制技术
Synchronization Technique of TDMA Satellite Communication in High-speed Movement
摘要
Abstract
This paper analyzes the influence of high-speed-caused Doppler drift and timing drift on TDMA satellite communication system,and proposes a synchronization technique of TDMA satellite communication system in high-speed movement, which realizes faster signal acquisition through navigation information from platform. Combining with features of TDMA satellite communication, the tracking and compensation of Doppler drift is implemented, meanwhile, the timing control is corrected according to the timing error estimated by Doppler drift. This technique eliminates high-speed effect and realizes fast access to network and synchronization without changing any technique configuration in present TDMA satellite communication network.关键词
