Dr. Michael Jensen and BYU graduate student Matthew Morris published ""Impact of receive amplifier signal coupling on MIMO system performance"" in the September 2005 issue of IEEE Transactions on Vehicular Technology; together with Research Associate Jon Wallace they published ""Superdirectivity in MIMO systems"" in the September 2005 IEEE Transactions on Antennas Propagation. Also in September, Dr. Jensen and Jon Wallace presented ""Recent advances in antennas and propagation for MIMO systems: multi-user networks and channel temporal variation"" at ICEAA'2005 in Torino, Italy and ""Measurement and characterization of the time variation of indoor and outdoor MIMO channels at 2.4 and 5.2 GHz"" at VTC'2005 in Dallas, Texas.
