Secrecy Analysis of RIS-Aided mmWave Systems over Independent Fluctuating Two-Ray Fading Channels

Asia-Pacific Conference on Communications
In this paper, we examine a millimeter-wave (mmWave) wiretap scenario where a multiple-antenna base station (Alice) communicates with a legitimate user (Bob) via a reconfigurable intelligent surface, while multiple colluding eavesdroppers (Eves) attempt ...
