Abstract
This study investigates physical layer authentication (PLA) in the downlink of massive MIMO systems. It is demonstrated that a multi-antenna rogue base station (BS) can impersonate the legitimate BS by injecting malicious signals during downlink transmission. Exploiting channel hardening, three PLA schemes are proposed, which are based on the large-scale fading coefficient and incorporate channel correlation for practical implementation. The false alarm and detection probabilities are analyzed. Additionally, a dual-threshold strategy for authentication decisions is developed. Finally, numerical simulations are conducted to validate the proposed schemes, elucidating the impact of system parameters on authentication accuracy.
期刊介绍：
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
