Relation between joint optimizations for multiuser MIMO uplink and downlink with imperfect CSI
Joint linear minimum sum mean-squared error (referred to as MSMSE) transmitter and receiver (transceiver) optimization problems are formulated for multiuser MIMO systems under a s...

Linear precoder design through cut-off rate maximization in MIMO-OFDM coded systems with imperfect CSIT
This paper proposes a linear transmitter design that aims at minimizing the packet error rate (PER) using partial channel state information at the transmitter (CSIT). The design is...

Scheduling and Codeword Length Optimization in Time Varying Wireless Networks
Abstract-- In this paper, a downlink scenario in which a singleantenna base station communicates with K single antenna users, over a time-correlated fading channel, is considered. ...
