摘要：安全预编码是一种信号处理技术，即发送端根据信道状态信息设计预编码矩阵，从而对信号进行预处理。该技术旨在保证合法用户通信质量的前提下，恶化窃听信道，在信息理论意义上实现无线通信系统的安全传输。认为物理层安全技术与移动通信的发展密不可分，利用毫米波信道稀疏特性开发物理层安全预编码技术，有望实现 5G 通信与安全一体化发展。

Abstract: Secure precoding is a signal processing technique. Precoding matrix is designed
at the transmitter to pre-process signal based on channel state information, aiming to ensure the communication quality for legitimate users and worsen the eavesdroppers'
channels. Secure transmission of wireless communication systems is realized in the sense of information theory. The physical layer security technology is inseparable from the development of mobile communication. By developing physical layer security precoding technology with millimeter-wave channel sparse characteristics, it is expected to realize the integrated development of 5G communication and security.
