A Relay Satellite‐Assisted Covert Communication Position Optimization in 6G Satellite Communication

ABSTRACT Satellite communication, a key technology in the 6G communication system, has advantages such as wide coverage, being unrestricted by geographical conditions, and large communication capacity. However, the communication process timely face eavesdropping from illegal warden due to the wireless broadcast characteristics of satellite communication. To solve this problem, we propose a relay satellite‐assisted covert communication on position optimization mechanics (RSCCPOM). Specifically, we construct a satellite communication countermeasure model and obtain the minimum detection error probability for the warden, and then optimize the position of relay satellite. Simulation results show that our RSCCPOM improve covert communication rate compared with existing work.
