多用户并行访问终端权限信息风险反馈仿真

Multi-User Parallel Access Terminal Authority Information Risk Feedback Simulation

对访问终端的权限信息进行风险反馈,能够有效提高多用户并行访问的运行效率。对权限信息进行风险反馈,需对权限信息时频取样,获得权限信息的包络幅值,以此完成权限信息的风险反馈。传统方法通过获取权限信息的幅频,根据幅频变化进行风险反馈,但忽略了对权限信息时频取样,导致了风险反馈效果不理想。提出基于模糊约束自适应波束的权限信息风险反馈方法,根据多用户并行访问终端权限信息风险反馈原理,构建权限信息传输结构模型,通过权限信息特征分布空间重构,获取权限信息特征时域和频域特征,并可得权限信息的风险反馈特征点,利用该特征点,获取权限信息风险反馈原理函数,结合时间顺序分析法,获得权限信息的包络幅值,进行权限信息聚焦反馈,实现多用户并行访问终端权限信息的风险反馈。实验结果表明,该方法对权限信息的风险反馈准确率较高,耗时较短。

The traditional method obtains the amplitude and frequency of authority information and feeds back risk based on the change of amplitude and frequency, but the method ignores the time-frequency sampling for authority information ,resulting in unsatisfactory risk feedback effect. In this paper, we focus on a method of feeding back risk of permission information based on fuzzy constrained adaptive beam. According to the risk feedback principle of authority information in multi-user parallel access terminal, we built the model of permission information transmission structure. Through the reconstruction of permission information feature distribution space, we obtained the feature of time domain and frequency domain of permission information, and then obtained the feature point of risk feedback of permission information. In addition, we used this feature point to obtain the principle function of risk feedback of permission information. Combined with the time sequence analysis method, we obtained the envelope amplitude of permission information. Finally, we focused on permission information feedback. Thus, we achieved the risk feedback of permission information in multi-user parallel access terminal. Simulation results show that the proposed method has higher accuracy and shorter time consumption in the risk information feedback.
