Abstract:

Zero-Forcing (ZF) algorithm is used to eliminate interference in small scale interference network. With the number of users increasing, the traditional ZF algorithm does not work effectively due to the fact that the channel matrix cannot provide sufficient dimensions to isolate interference. In this paper, we propose a Coordinated Zero-Forcing Beamforming with Clustering(CZFC) scheme to improve the defects of traditional ZF algorithm. Firstly, users are partitioned into clusters according to clustering rule that inter-cluster interference can almost be neglected, then CZF is applied to each cluster, respectively. Simulation results show that the proposed scheme can significantly increase system capacity, and at the same time, the proposed algorithm has low complexity. In most cases, it will be able to converge after three iterations.
