摘要
针对随机异构网络频谱资源紧张及微基站层安全性能不足的问题，通过在微基站层引入多天线全双工中继辅助微基站用户通信，由此提高网络的整体安全性能。基于随机几何理论，构建针对该网络的安全性能分析模型，推导出了用户接入中继基站或宏基站、中继接入微基站的安全中断概率闭式表达式；基于此进一步给出了系统全局安全中断概率闭式表达式，以评估系统参数对其安全性的影响。仿真分析了宏基站功率和天线数、中继功率和天线数，以及两者的密度对网络安全性能的影响。仿真结果验证了引入多天线全双工中继能够提高所研究网络的安全性能。
Abstract
To alleviate the spectrum shortage problem and security threats in heterogeneous network (HetNet)
multi-antenna full-duplex relay was introduced for communication between femto base station (FBS) and legitimate user.With the aid of multi-antenna full-duplex relay in FBS network
the secrecy performance of HetNets could be improved.Under a stochastic geometry framework
the fundamental analysis model to evaluate the secrecy performance in multi-antenna full-duplex relay aided HetNet was set up.To be specific
the exact expressions for the secrecy outage probability of the typical user
serving relays and HetNet were derived respectively.Then
based on the theoretical analyses and simulation results
the influences of transmit power and antenna number of both macro base station and FBS on secrecy performance in HetNet were examined.Finally
the results show that introducing multi-antenna full-duplex relay for FBS networks improves the secrecy performance of HetNet.
