Abstract

This paper mainly focuses on the single-cell multi-user full-duplex system. Both the base station and the users adopt the full duplex (FD) technology. The interference alignment (IA) is introduced in the system to resolve the interference from the intra-user and the inter-users. Based on the thought of the user virtual splitting, the FD-BS-FD-user system is equivalently processed. Then, a set of cycle IA equations are designed to reach the optimal system degree of freedom (DoF). The simulation shows that the cycle IA scheme can reach the desired result.
