Atmospheric phase fluctuation effect on communication quality in space uplink optical communciation

Abstract

The BER performance with consideration of phase fluctuation effect in space optical communication is investigated. When the phase fluctuation effect is considered, BER definitely increase which leads to the worse communication quality. Based on numerical simulation, BER is sensitive to the higher level of zenith angle. There exists the optimal point of divergence angle in practical system and this point turns to be lower if phase fluctuation effect is considered. After we analyze different BER performance in different wavelengths, we can know that 1550nm of wavelength is always the better choice for great communication quality. The work is beneficial for increasing the communication quality and designing the practical communication system.
