Research on interference alignment for heterogeneous network
异构无线网络干扰对齐技术研究

HetNet composed of macrocell and picocell will play an important role in future cellular system, and it has potential to drastically improve the capacity of wireless network. With the deployment of picocells, CCI is more and more serious in the heterogeneous network. Thus, interference suppression is very meaningful for heterogeneous network. Recently, IA, which can obtain the optimal transmitting DoF, is explored to maximize the capacity of the network. Based on the muticell IA algorithm, this paper proposed an optimized IA scheme for heterogeneous network. Simulation results show that the presented IA scheme can improve the capacity of HeNet and reduce the implementation complexity.
