发布时间：2018-10-26 13:30
【摘要】：密集异构蜂窝网络节点布置的随机性、动态性、复杂性等特点,导致实际场景中该系统的安全性能受非理想信道估计的影响更严重,然而目前对该系统安全性能的研究主要集中于理想场景,缺乏在非理想场景中的研究。针对这一问题,该文从密集异构蜂窝网自身结构及实际部署的特点出发,分析了信道估计存在误差时系统的安全性能。首先基于随机几何对系统建模,推导了非理想情况下K层密集异构蜂窝网的安全中断概率;然后分析了部分参数对系统安全性能的影响;最后,通过仿真验证了理论推导的有效性。
[Abstract]:The randomness, dynamics and complexity of the node arrangement in dense heterogeneous cellular networks make the security performance of the system more seriously affected by the non-ideal channel estimation. However, the current research on the security performance of the system is mainly focused on the ideal scenario, lack of research in the non-ideal scenario. To solve this problem, this paper analyzes the security performance of the system when channel estimation errors exist, based on the characteristics of dense heterogeneous cellular networks and their actual deployment. Firstly, based on the stochastic geometry model, the security interruption probability of K-layer dense heterogeneous cellular network is derived, and then the influence of some parameters on the security performance of the system is analyzed. Finally, the validity of the theoretical derivation is verified by simulation.
