Abstract

The invention discloses a two-dimensional robust beamforming method under MISO eavesdropping channel based on interruption probability constraint. The method proposes a robust beamforming scheme for MISO eavesdropping channel. Relaxation and Bernstein‑type inequality transform non-convex problems with outage probability constraints into a series of semi-definite programming problems, and use Gaussian variables to obtain the optimal robust beamforming design, which can effectively improve the security rate of communication systems and reduce eavesdropping users. The eavesdropping ability improves the security of the communication system.

Description

technical field [0001] The invention belongs to the technical field of physical layer security in wireless communication, and in particular relates to a two-dimensional robust beamforming method under a MISO wiretapping channel based on interruption probability constraints. Background technique [0002] In recent years, the continuous development of wireless communication technology has enabled people to access communication networks anytime and anywhere. However, the broadcast nature of wireless communication means that all nodes within the transmission range can receive the signal sent by the source, and the information of legitimate users is easily obtained by eavesdropping users. Therefore, it is particularly important to ensure the secure transmission of wireless communication [1]. Compared with traditional encryption methods, physical layer security aims to use the physical layer characteristics of wireless communication, such as noise, fading, etc., to ensure the sec...
