On the Optimality of Multiuser Zero-Forcing Precoding in MIMO Broadcast Channels

In this paper, we consider a multiuser Gaussian broadcast channel where the base station and the users both are equipped with multiple antennas. The problem of optimal zero-forcing (ZF) precoding design subject to sum power constraint is discussed. Block diagonalization (BD) is applied as the ZF pre...
