摘　　要：首先从理论上分析了正弦振动对卫星光通信中接收误码率的影响。在此基础上 ,提出并采用了“用计算机控制驱动压电晶体模拟星上振动” ,设计模拟实验对理论分析结果进行了验证。最后 ,对实验中出现的问题给出了解释 ,并对今后卫星光通信系统的设计提出了建议。The influence of sine vibration on bit error rate in intersatellites optical communications was analyzed. Based on the work, the theoretical result was testified through the simulation experiment in which the piezocrystal controlled by the computer was used to simulate the sine vibration.Finally, the problem coming from the experiment was explained and some advice was given to improve the intersatellites optical communications system.
