Soft Actor-Critic Based Power Control Algorithm for Anti-jamming in D2D Communication

In this paper, we study the anti-jamming problem in device-to-device (D2D) communication. D2D communication will be interfered by cellular users because of multiplexing uplink. When faced with malicious interference from outside, it is necessary to carry out reasonable interference control while ensuring the communication between cellular users and D2D users. Aiming at this problem, a power control communication anti-jamming algorithm based on Soft Actor-Critic (SAC) is proposed. By modeling the transmitter of D2D users as an agent, the overall throughput of the system is improved and the influence of external malicious interference is reduced while ensuring the signal-to-noise ratio of D2D users and cellular users. Compared with DQN (Deep Q-network) and random methods, the proposed algorithm can obtain higher system throughput and faster convergence speed in the face of sweep interference, and can show better anti-jamming effect.
