Research Summary

My current research is at the intersection of communication theory, signal processing, and information theory. A primary research thrust is the advancement of MIMO (multiple-input multiple-output) communication technology including space-time coding, efficient receiver algorithms, channel quantization, synchronization, scheduling algorithms, cross-layer design for MIMO ad hoc networks, and antenna design. I use theory, simulations, and prototyping to validate research ideas. I am also interested in applied mathematics including matrix theory and applications of matrix theory to communication problems. Currently I am developing signal processing algorithms that operate on the Grassmann manifold with applications to communication, graphics, and data mining.
