A Two-Dimensional Linear Pre-Transformed (2DLPT) MIMO-OFDM System
— We propose an open-loop two-dimensional linear pre-transformed (2DLPT) multiple-input multipleoutput (MIMO) orthogonal frequency division multiplexing (OFDM) system. The nT N Ã...

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...
