Problems solved by technology

If full-duplex D2D users are used for cooperative relay, the physical layer security performance of cellular users can be improved to the greatest extent, but the transmission of D2D own data cannot be realized. Therefore, the joint use of D2D cooperative relay and friendly interference mode can maximize Taking into account the physical layer security performance of cellular users and the transmission requirements of D2D users

Abstract

The invention provides a Q learning-based D2D cooperative relay power control method under full duplex active eavesdropping. In a condition of full duplex active eavesdroppers existing in a cellular system, a Q learning-based hierarchical learning algorithm is adopted, the jamming power of the active eavesdropper and the transmitting power of D2D cooperative relay and friendly jamming are updatedsuccessively, and the physical layer security performance of the cellular system is thus enhanced.

Description

technical field [0001] The present invention relates to a Q-learning-based D2D cooperative relay power control method under full-duplex active eavesdropping, specifically a method for improving the security performance of a cellular network physical layer by adopting a Q-learning-based D2D cooperative relay power update strategy. The invention belongs to the technical field of power control in wireless communication. Background technique [0002] According to information theory, when the channel gain between legal transceivers is better than the channel gain between legal transmitters and eavesdroppers, the security of sending information can be perfectly guaranteed without being intercepted and decoded by eavesdroppers . This is the basic premise to ensure the security performance of the physical layer of information, and it is also the direction to improve the security of the physical layer. Many technologies, including multi-antenna, cooperative relay, and artificial int...
