Recent advances in self-interference cancellation enable radios to transmit\nand receive on the same frequency at the same time. Such a full duplex radio is\nbeing considered as a potential candidate for the next generation of wireless\nnetworks due to its ability to increase the spectral efficiency of wireless\nsystems. In this paper, the performance of full duplex radio in small cellular\nsystems is analyzed by assuming full duplex capable base stations and half\nduplex user equipment. However, using only full duplex base stations increases\ninterference leading to outage. We therefore propose a mixed multi-cell system,\ncomposed of full duplex and half duplex cells. A stochastic geometry based\nmodel of the proposed mixed system is provided, which allows us to derive the\noutage and area spectral efficiency of such a system. The effect of full duplex\ncells on the performance of the mixed system is presented under different\nnetwork parameter settings. We show that the fraction of cells that have full\nduplex base stations can be used as a design parameter by the network operator\nto target an optimal tradeoff between area spectral efficiency and outage in a\nmixed system.\n
