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.

存在不完善反馈的情况下多用户多窃听者多输入多输出（MIMO）系统的物理层安全性

在这项工作中，我们使用最大比率组合在基站（BS）上使用选择传输（ST）分析多用户（MUS）多输入多输出多监听器（MIMOME）无线网络的物理层安全性（PLS）（MRC）处于不相关瑞利衰落信道上的合法用户（LU）接收者和非法用户的接收者。在这种情况下，多个用户同时与BS通信，多个窃听用户可能会拦截传输。接下来，在存在不完善的信道状态信息（ICSI）的情况下，针对非零保密容量（PNZSC）和保密中断概率（SOP），驱动精确的闭式表达式。最后，
