针对多环境因子对大气能见度的影响，提出了一种在自然环境多因子背景下的量子卫星通信纠缠波分接入策略。当每对地面通信站分配量子密钥时，它们会通过量子卫星形成不同波长的纠缠对，并根据不同波长的量子纠缠，将众多地面通信站接入同一颗卫星。仿真结果表明，在大气湿度和雾霾粒子浓度相同的情况下，采用纠缠波分接入技术，可使系统的信道容量增大，量子误码率从3.3415×10-3减小到2.243×10-3，由大气能见度的影响所导致的误码率的增幅减小。由此可见，在环境多因子背景下的纠缠波分接入策略对量子卫星通信性能有明显的改善。

Aiming at the impact of multiple environmental factors on atmospheric visibility, this study proposes an entangled wave division access strategy of quantum satellite communication under the background of multiple factors in a natural environment. When each pair of ground stations distributes quantum keys, they can form entanglement pairs of different wavelengths through the quantum satellite. According to quantum entanglement of different wavelengths, many ground stations can connect to the same satellite. The simulation results show that under the same atmospheric humidity and haze particle concentration, the system’s channel capacity increases, and the bit error rate decreases from 3.3415×10-3 to 2.243×10-3. The increase in the bit error rate caused by atmospheric visibility factors will also decrease. Thus, in the environmental multifactorial context, the entangled wave-split access strategy can improve the quantum satellite communication performance.
