Multi-user multiple-input and multiple-output (MU-MIMO) transmission has been extensively studied to enhance the spectral efficiency of wireless communication systems. The performance of MU-MIMO suffers due to the presence of residual multi-user interference. Linear interference cancellation can offer excellent performance when a large number of antennas are available. This, however, is impractical in a mobile station. In this paper, we apply a collaborative interference cancellation scheme todoi:10.1587/comex.4.155 fatcat:n2kdp2w3krgz7nzqbbmsznjsay
