基于中继间干扰消除的轮流转发系统安全传输方案
Successive relaying secure transmission scheme based on inter-relay interference cancellation
摘要
Abstract
A secure scheme based on inter-relay interference cancellation was proposed to solve untrusted relay eave-sdropping problem in successive relaying systems. First inter-relay interference between trusted relay and untrusted relay was exploited as artificial noise to degrade untrusted relay's eavesdropping condition, then interference iterative cancella-tion was adapted to improve signal quality at legitimate user by making use of correlation between signals in time domain. Based on this, a quick power allocation algorithm aiming to minimize untrusted relay's sum rate was proposed. Analysis and simulation results show that the proposed scheme suppress untrusted relay's eavesdropping without loss of commu-nication efficiency, a promotion of at least 2 bit·s?1·Hz?1 in secrecy rate can be observed.关键词
