Collaborative Secret and Covert Communications for Multi-User Multi-Antenna Uplink UAV Systems: Design and Optimization

Motivated by diverse secure requirements of multi-user in uncrewed aerial vehicle (UAV) systems, we propose a collaborative secret and covert transmission method for multi-antenna ground users to UAV communications. Specifically, based on the power domain non-orthogonal multiple access (NOMA), two g...
