Multiple antenna wireless communication systems, also known as multiple-input multiple-output (MIMO) systems, are very promising for the next generation wireless communication systems, since they can support high data rates with great reliability by taking advantage of the spatial diversity provided by using multiple antennas at the transmitter and/or the receiver. In fact, MIMO systems are now part of wireless communication standards, e.g. IEEE 802.11 Wireless LAN, IEEE 802.16 Wireless MAN standard.
MIMO systems is a relatively new area of research, where initially main focus was on single user systems. For the widespread adoption of MIMO technologies, more work needs to be done about characterizing the gains from multiple antennas in a multiuser environment and developing computationally efficient algorithms that can provide performance gains predicted by the information theoretic studies.
I am mainly interested in investigating the information theoretic limits of multiuser MIMO systems and developing transmission schemes that can operate close to these limits. Information about current research projects can be found here.
