Beamforming Design and Covert Performance Analysis for Full-Duplex Multiantenna System
In this work, a wireless covert communication system with full-duplex (FD) multiantenna receiver is considered.In order to improve the convert performance of the wireless communication system in the FD mode, a scheme based on selection combining/zero forcing beamforming (SC/ZFB) is proposed.More specifically, a covert message receiver with a FD mul
