Broadcast Channels with Delayed Finite-Rate Feedback: Predict or Observe?
Most multiuser precoding techniques require accurate transmitter channel state information (CSIT) to maintain orthogonality between the users. Such techniques have proven quite fr...

Multiuser MIMO Downlink with Limited Feedback Using Transmit-Beam Matching
— The multiuser multiple-input multiple-output (MIMO) broadcast channel uses multiple antennas at the transmitter to simultaneously deliver information to multiple users. Despite...

High SNR Analysis for MIMO Broadcast Channels: Dirty Paper Coding vs. Linear Precoding
We study the MIMO broadcast channel and compare the achievable throughput for the optimal strategy of dirty paper coding to that achieved with sub-optimal and lower complexity lin...
