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...

Diversity Analysis of coded SVD Schemes for MIMO Spatial Multiplexing Systems
— When channel state information (CSI) is available at both transmit and receive sides, singular value decomposition (SVD) converts the MIMO channel into parallel subchannels. It...
