| Abstract: | Techniques for communication over flat multi-input, multi-output (MIMO) channels are well established when either perfect channel state information or no channel state information is available at the transmitter. However, communication over channels where the transmitter has access to partial or imperfect information has received less attention. If explored, such information could improve system performance. In this paper, we propose a simple system design scheme, that approximately maximizes the data rates of MIMO communication systems where imperfect channel estimates are available at the transmitter. The presented algorithm is computationally attractive and gains compared with systems not exploring this information are demonstrated. | ||
