  • 摘要: 大規(guī)模MIMO系統(tǒng)采用空分多址可以提高系統(tǒng)吞吐量,同時利用多用戶下行信號的相互協(xié)作可以對竊聽者造成疊加干擾,帶來了天然的安全增益。但目前該系統(tǒng)的物理層安全研究仍采用傳統(tǒng)的人工噪聲方案,忽略了多用戶信號干擾帶來的安全增益,造成嚴重的功率浪費。針對這一問題,該文分析了多用戶信號干擾對系統(tǒng)可達平均安全速率和平均安全能效的影響,給出了系統(tǒng)的最佳接入用戶區(qū)間。研究發(fā)現(xiàn),在系統(tǒng)接入用戶數(shù)較少和用戶數(shù)較多時,系統(tǒng)安全能力較弱,針對此分別提出了N波束加擾和基于用戶位置的用戶調度的自適應安全傳輸策略。最后通過仿真驗證了理論推導和所提策略的有效性,利用該文所提策略,能夠保證系統(tǒng)天然安全能力不足時的安全通信。
