  • Because of the vibration of the satellite,the bit error rate(BER) will be influenced in a space optical communication system.The influence of different types of vibrations should be analyzed when discussing the influence of the satellite vibration on bit error rate.The satellite vibration is firstly simplified to a harmonic motion model.Then square-wave,triangle-wave and backle-wave types of vibrations are respectively analyzed.For sine vibration,the analyzing results show that BER is the function of vibration amplitude and has no relation with vibration frequency when the duration is full period.With vibration amplitude increasing,BER rapidly increases.When the duration is not full period,following increase of time,BER fluctuates and the change of BER is less and less and tendency a constant with amplitude.

Abstract: Because of the vibration of the satellite,the bit error rate(BER) will be influenced in a space optical communication system.The influence of different types of vibrations should be analyzed when discussing the influence of the satellite vibration on bit error rate.The satellite vibration is firstly simplified to a harmonic motion model.Then square-wave,triangle-wave and backle-wave types of vibrations are respectively analyzed.For sine vibration,the analyzing results show that BER is the function of vibration amplitude and has no relation with vibration frequency when the duration is full period.With vibration amplitude increasing,BER rapidly increases.When the duration is not full period,following increase of time,BER fluctuates and the change of BER is less and less and tendency a constant with amplitude.
