Physical Layer Security for STAR-RIS-Assisted NOMA Backscatter Communications Against Multiple Eavesdroppers

Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) have emerged as a transformative technology for achieving omnidirectional coverage in smart radio environments, enabling energy-efficient and spectrally efficient wireless communications. When integrated with ambient backscatter c...

Efficient Federated LLM Framework for Intelligent IoMT Management

Generalized Coordinated Learning for Radio Resource Management in Dense D2D Networks

Dense device-to-device (D2D) communication networks with a huge number of directly communicating devices necessitate an efficient radio resource management to maximize network performance. To this end, we first propose a novel intelligent channel reuse based on deep deterministic policy gradient (DDPG) to maximize effi...
