摘　　要：针对传统光纤多方量子通信信道参数自适应调整方法由于信道参数能力较差,导致调整后的信道误比特率较高,影响通信信道调整效果的问题,设计了光纤多方量子通信信道参数自适应调整方法.采用MUSIC算法提取通信信道参数并设定为预设理想参数,使用惯性权重算法构建自适应调整模型,实现通信信道参数自适应调整.仿真结果表明:与其他2种传统方法对比,此方法的误比特率较低,对调整误差具有降低作用,使用效果较好.In view of the traditional optical fiber multiparty quantum communication channel parameters adaptive adjustment method due to the channel capacity is poor,leading to higher adjusted channel bit error rate and influencing the effect of communication channel adjustment problems,the fiber multiparty quantum communication channel parameter adaptive adjustment method is designed.Using MUSIC algorithm to extract the communication channel parameters and set to the default ideal,adaptive adjustment model is established using inertia weight algorithm to realize the communication channel parameter adaptive adjustment.The simulation results show that compared with other two traditional methods,this method of bit error rate is low,the adjusting error is lower,it is better to use.
