Performance of Multi-User MIMO Precoding with Limited Feedback over Measured Channels
Abstract—In multi-user multiple-input multiple-output (MUMIMO) systems, channel state information at the transmitter (CSIT) allows for multi-user spatial multiplexing and thus in...

Limited feedback for multi-antenna multi-user communications with Generalized Multi-Unitary Decomposition
– In this paper, we propose a decomposition method called Generalized Multi-Unitary Decomposition (GMUD) which is useful in multi-user MIMO precoding. This decomposition transfor...
