Abstract

Summary: In this work, we analyze the physical layer security (PLS) for a multiuser (MUS) multi‐input multi‐output multi‐eavesdropper (MIMOME) wireless network using selection transmission (ST) at the base station (BS) with maximum ratio combining (MRC) at both of the receivers, receivers of legitimate users (LUs) as well as the receivers of illegitimate users over an uncorrelated Rayleigh fading channel. In this scenario, multiple users communicate to a BS at the same time multiple eavesdropper user may intercept the transmission. Next, we drive exact closed‐form expression for probability of nonzero secrecy capacity (PNZSC) and secrecy outage probability (SOP) in the presence of imperfect channel state information (ICSI). At last, we present the simulation results to authenticate the analytical results and analyze the impact of ICSI on PLS of MUS‐MIMOME system. Abstract : In this work, we analyze the impact of imperfect channel state information (ICSI) on physical layer security (PLS) for a multiuser (MUS) multi‐input multi‐output multi‐eavesdropper (MIMOME) wireless network. Here, we consider selection transmission and maximum ratio combining (ST/MRC) at base station (BS) and at both of receivers, receiver of legitimate users (LUs) as well as at the receivers of illegitimate users. For this work, we consider uncorrelated Rayleigh fading channel for data transmission for both the channels. We assume uncertainty into CSI is due to feedback delay (FD). At last, we analyze the impact of ICSI on probability of nonzero secrecy capacity (PNZSC) and secrecy outage probability (SOP).
