Abstract
In this paper we study propagation properties of multi-user MIMO systems in narrow indoor corridor environments. From extensive channel measurements, it is observed that the channels to different users often experience very high or very low orthogonality. As a consequence, the gain of optimal dirty-paper-coding, or any other coding scheme, over linear processing techniques becomes insignificant.
