This paper studies the physical (PHY)-layer security
performance in full-duplex (FD) multiple-input multipleoutput
(MIMO) small-cell networks. Here, we take into account
(i) residual self-interference (SI) over Rician fading channels,
and (ii) mutual-interference (MI) under successive interference
cancellation (SIC) mechanism. Considering linear zero-forcing
(ZF) beamforming, the downlink (DL) and uplink (UL) average
secrecy rates under both scenarios of passive and colluding
eavesdropping are derived. Our findings indicate that the FD
functionality can provide substantial improvements in the PHYlayer
security performance, especially with the aid of MIMO
communications and interference cancellation solutions.
