基于有限反馈的非可信中继系统的物理层安全性能分析
Performance Analysis of Physical Layer Security of Untrusted Relay System Based on Limited Feedback
摘要
Abstract
Under the condition of partial channel state information that is obtained from limited feedback,a physical layer se-curity transmission technique is investigated for amplify-and-forward untrusted relay systems,where the positive secrecy capacity is obtained through the artificial noise interference information transmitted by the destination node.Closedform expressions for security outage probability and transmission outage probability are derived,and the impacts of the number of feedback bits on security and reliability are analyzed.Furthermore,an adaptive selection scheme for the optimal number of feedback bits is proposed in order to si-multaneously satisfy both required security and reliability.关键词
