A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...

Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

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...
