Heterogeneous networks (HetNets) that incorporate small cells save energy effectively because the small cells have lower transmission and operational power consumptions. However, the performance of HetNets depends heavily on reducing the interference. In this paper, we investigated interference cancellation (IC) with the aim of developing a decorrelating receiver. We focused on millimeter wave small cells systems in which multiuser multiple-input multiple-output transmission was utilized. We began by suppressing the interference in the multiple antennas mode by means of well-known zero-forcing and a minimum mean square error algorithm. Then, we investigated more active IC. To further reduce the impact of interference in HetNets, we developed a hybrid HetNets paradigm. Finally, we used simulations to achieve performance evaluation and comprehensive comparative analysis. Extensive numerical results verified the effectiveness of the proposed schemes. This research provides an efficient solution for suppressing multiple access interference and improving the throughput in hybrid HetNets.
