Improved information outage rate in certain MIMO systems

We propose a simple class of encoding/decoding techniques that can be used to improve the information outage rate of certain multiple-input-multiple-output (MIMO) systems. Gains in outage rate can be achieved at low to moderate signal-to-noise ratios in MIMO systems that have fewer receive antennas than transmit antennas. This performance improvement is due to extra "virtual" receive antennas that are created with low-complexity signal processing. A simple space-time block code system using virtual receive antennas is also investigated
