Movable Antenna-Enabled Secure Communications Against Simultaneous Jamming and Eavesdropping Attacks

This paper focuses on a movable antenna (MA) enabled downlink multi-user communication system, where a base station (BS) aims to transmit messages to multiple users with a malicious jammer and multiple eavesdroppers posing threats. Both the BS and the users feature MAs, while the jammer and eavesdroppers make use of fixed-position antennas (FPAs). In accordance with the BS’s transmission power budget, designated MA moving regions, and minimum spacing between transmitting MAs, the system’s minimu
