Reconfigurable intelligent surface (RIS) has shown significant advantages in improving energy efficiency (EE) and ensuring secure communications cell-free massive multiple-input multiple-output (CF mMIMO) networks. In this letter, order to enable RIS fully play its role explore the inherent of RIS, we design a joint phase adjustment power control scheme optimize EE network, while coping with pilot attacks. An Improved DDPG-PER algorithm, which integrates batch normalization (BN), prioritized...
This paper addresses the secure communication problem in a distributed active-passive reconfigurable intelligent surface (RIS) assisted multiple-input single-output (MISO) scenario with single-antenna malicious eavesdropper. The objective is to maximize secrecy rate of legitimate user under constraints on base station (BS) power and RIS amplification coefficients. study investigates joint optimization algorithm for BS beamforming phase-shift matrices. To address complex non-convex fractional...
