Precoder Designs for MIMO Broadcast Channels with Imperfect CSI
—In this paper, we propose two robust precoder designs for multiple-input multiple-output (MIMO) broadcast channels with imperfect channel state information (CSI). First, we cons...

On the Rate Duality of MIMO Interference Channel and Its Application to Sum Rate Maximization
In this paper, we establish a rate duality between the forward and reverse links of MIMO interference channel, where the reverse links are obtained by exchanging the roles of trans...
