Transmission of common, public and confidential messages in broadcast channels with multiple antennas
Abstract-- We study the Gaussian multiple-input multipleoutput (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the...

MIMO Broadcast Scheduling with Limited Feedback
Abstract— We consider multiuser scheduling with limited feedback of partial channel state information in MIMO broadcast channels. By using spatial multiplexing at the base statio...

MIMO Multiple Access Channels with Noisy Channel Estimation and Partial CSI Feedback
Abstract—We consider correlated MIMO multiple access channels with block fading, where each block is divided into training and data transmission phases. We find the channel esti...

Limited Feedback Precoding in Realistic MIMO Channel Conditions
— MIMO system design for real applications requires that factors such as channel estimation errors, feedback quantisation and realistic channel responses be taken into account. L...

MIMO Broadcast Channels with Spatial Heterogeneity
We develop a realistic model for multiple-input multiple-output (MIMO) broadcast channels, where each randomly located user's average SNR depends on its distance from the tran...
