Block diagonalization (BD) is a linear precoding technique for multiuser multi-input multi-output (MIMO) broadcast channel that sends multiple interference free data streams to different users in the same cell. In this paper, we investigated the capacity of a multiuser multiple input multiple output (MIMO) system employing the block diagonalization scheme in presence of spatial correlation. The optimized diagonalization technique with power allocation scheme is proposed and verified.
