Abstract

Full-duplex is a promising technology in the next generation wireless communication system to improve the spectrum efficiency by receiving and transmitting simultaneously in the same channel. In this paper, we investigate resource allocation problem aiming to enhance physical layer security of full-duplex cellular system with half-duplex (HD) users and full-duplex (FD) base station. The full-duplex resource allocation is formulated as 3-dimentional one-to-one matching problem and an iterative Hungarian method (IHM) is proposed to solve the matching problem. Simulation results show that the IHM can achieve optimum solution of the integer optimization problem while maintaining a rather low computational complexity.
