【摘要】：文章針對外部竊聽者與不可信中繼同時存在的協(xié)同通信系統(tǒng),采用人工干擾節(jié)點對內(不可信中繼)、外部竊聽者進行干擾來提高系統(tǒng)的安全性能。分析了干擾節(jié)點個數(shù)對系統(tǒng)安全通信的影響,并在此基礎上討論了為達到最佳干擾效果,系統(tǒng)中各類節(jié)點間的功率分配問題,得到了系統(tǒng)總發(fā)送功率一定條件下的最佳干擾節(jié)點個數(shù)配置與干擾分功率方案。
[Abstract]:In this paper, we aim at the cooperative communication system in which external eavesdroppers and untrusted relays exist at the same time. In order to improve the security performance of the system, artificial interference nodes are used to improve the security performance of the system. The influence of the number of interference nodes on the security communication of the system is analyzed, and on the basis of this, the optimal jamming effect is discussed. In this paper, the optimal number of interference nodes and the scheme of interference power distribution are obtained under the condition of the total transmission power of the system.
