Abstract

Multi-site multi-user multiple input multiple output (MS-MU-MIMO) is a key technology to construct the next generation high performance mobile communication networks; however, in MS-MU-MIMO systems, co-channel interference (CCI) occurred at cell edges significantly reduce user throughput. To overcome this problem, in this paper, we proposed a MS-MU-MIMO system with block diagonalization (BD)-based interference cancellation. Overall downlink performances of the proposed system and the traditional MS-MIMO system are compared through computer simulation, and the simulation results show that the proposed system can improved user throughput.
