摘要
卫星光通信中,两个光通信终端同时对来自对面终端的光束进行跟踪,跟踪误差为时间和统计上的联合随机变量.讨论了跟踪误差对光功率接收的影响,对双向跟踪的稳态条件进行了估计.最后,以开关键控脉冲调制和直接检测方式的卫星光通信为例,通过仿真分析了跟瞄误差对光通信的影响.
Abstract
Two terminals in intersatellite optical communications (IOC) track each other, the tracking errors should be joint random variables in time and statistics. The influences of the tracking errors on the optical receiving are analyzed, and the stability state condition is estimated At last, for on-off keying modulation and direct detection in IOC, the influences of the tracking errors on the optical communication are simulated.
