Abstract(in English) | In a downlink (broadcast channel) of multiuser MIMO systems, we need to suppress the inter-user interference (IUI). It is known that block diagonalization and MMSE precoding are typical schemes for IUI suppression. In addition, we have proposed generalized block diagonalization (GBD) to achieve both high transmit diversity gain and IUI space limiting with a partial nulling concept. In this paper, we evaluate the impact of channel estimation error on the these precoding methods by computer simulations for BER performance. |
