Secure Massive MIMO Relaying Systems in a Poisson Field of Eavesdroppers

Abstract: Abstract-A cooperative relay network in the presence of eavesdroppers, whose locations are distributed according to a homogeneous Poisson point process, is considered. The relay is equipped with a very large antenna array and can exploit maximal ratio combing (MRC) in the uplink and maximal ratio transmission (MRT) in the downlink. We consider a realistic model that the channel state information of every eavesdropper is not know as eavesdroppers tend to hide themselves in practice. The destination is thus in a… Show more

“…For secure transmission issues with relay collaboration, most of the existing works [21][22][23][24][25][26][27][28][29][30][31][32][33]37] do not simultaneously address the power allocation, resource utilization, and multiple relay selection in a scenario where information leakage happens at both transmission phases in massive MIMO networks with limited time-frequency resources. In this paper, we present a cooperative transmission mode for the security issue of massive MIMO two-way relay networks.…”

“…By exploiting wireless transmission properties, physical-layer security has attracted considerable attentions in massive MIMO networks [16,17]. Several efforts such as artificial noise [18][19][20], antenna/relay selection [21][22][23], and cooperative strategies [24][25][26][27] have been employed to deal with the information leakage by eavesdroppers. The utilization of antenna correlation diversity was demonstrated to improve the secrecy rate of massive MIMO systems [19].…”
