摘要

本文研究了存在无源窃听器的大规模多输入多输出(MIMO)非正交多址(NOMA)网络的保密性能。基于上行训练阶段估计的信道状态信息，基站使用强制零预编码对机密信息进行预编码。然后，解析导出下行数据传输中各用户设备的遍历保密率。计算机模拟验证了分析的正确性。讨论了不同系统参数对保密性能的影响。

Performance Analysis of Ergodic Secrecy Rates in Massive MIMO-NOMA Networks with Zero-Forcing Precoding

In this paper, we investigate the secrecy performance of massive multiple-input multiple-output (MIMO) nonorthogonal multiple access (NOMA) networks with the presence of a passive eavesdropper. Based on the estimated channel state information in an uplink training phase, the base station precodes the confidential information using zero-forcing precoding. Following this, the ergodic secrecy rate of each user equipment is analytically derived in the downlink data transmission. Computer simulations are performed to validate the correctness of our analysis. Discussions on the impacts of different system parameters on the secrecy performance are also provided.
