摘要: 研究了基于协作多点网络的非正交多址系统的物理层安全问题，在协作多点网络中存在一个窃听者且中继采用放大转发策略的场景下，对NOMA-CoMP系统的物理层安全性能进行理论分析，推导了全局保密中断概率和各子信道保密中断概率的闭式解。经验证，NOMA-CoMP系统的物理层安全性能优于非CoMP的多小区NOMA系统。
Abstract: The physical layer security of non-orthogonal multiple access systems based on cooperative mul-ti-point network is studied. Considering the presence of eavesdroppers in a coordinated multi-point network, the relay adopts an amplification and forwarding (AF) strategy to analyze the physical layer security performance of NOMA-CoMP system and derive the expression of the global secret outage probability and the secret outage probability of each subchannel. It is verified that the physical layer security performance of the NOMA-CoMP system is better than that of the non-CoMP multi-cell NOMA system.
