Influence of Different Mixing Patterns of Haze Particles and Water Cloud Particles on the Performance of Quantum Satellite Communication
In order to analyze the influence of different mixing patterns of mixed particles on the quantum satellite communication, according to the spectral distribution function of hazeparticles and water-cloud particles and the extinction factor in different mixing patterns, the attenuation relationship of the quantum satellite communication channel in external mixing mode was proposed, and the Core-shell channel attenuation model was established. Thus the quantitative relation among the volume ratio of the mixed particles, fidelity of quantum communication and channel bit error rate were analyzed and simulated. The simulation results show that, when the volume ratio of mixing particles is 0.2 (0.8), the channel capacity, channel average fidelity and the channel bit error rate of external mixing mode will be 0.39 (0.27), 0.8 (0.8) and 0.003 (0.009), respectively; the channel capacity, channel average fidelity and the channel bit error rate of external mixing mode will be 0.8 (0.21), 0.94 (0.81) and 0.018 (0.021), respectively. It can be seen that the influence of different mixing modes of haze aerosol and water cloud particles on the communication performance of quantum satellite is different. Therefore, the parameters of the communication system should be adjusted adaptively based on the different mixing patterns to improve the reliability of the quantum satellite communication.
