In three dimension multiple-input multiple-output (3D MIMO) systems, large number of antennas are arranged at base station (BS) to obtain high spectral efficiency and large throughput. But increase of BS antennas also enhances the computational complexity of the multiuser precoding algorithm such as block diagonalization (BD) significantly. For the dimension increase of channel matrix, various ways...
The combination of multiple-input multiple-output (MIMO) and relay technology promises to increase coverage and system capacity, while the actual performance of MIMO relay system highly depends on the practical channel conditions. Based on the propagation measurement data in urban environment, we deal with the capacity evaluation for a two-hop amplify-and-forward MIMO relay channel in this paper....
