Recently, we proposed a multi-user spatial multiplexing technique called the minimum mean square error filtering combined with singular value decomposition (MMSE-SVD) for a distributed multiple input multiple output (MIMO) network. Multi-user MMSE-SVD applies the MMSE filter at macro base station (MBS) to suppress inter-user interference (IUI) and interantenna interference (IAI), while the eigenmode filter constructed by SVD at user equipments (UEs) to suppress IAI. To improve the link capacity in multicell environment, the inter-cell interference (ICI) from adjacent macro-cells is taken into account in generating the MMSE filter. In this paper, we apply multi-user MMSE-SVD with ICI information to OFDM downlink and SC uplink to discuss the impact of number of multiplexed UEs.
