Welcome to the Wireless Science and Engineering Lab

Our research includes understanding, evaluating, and designing various portions of wireless communication systems, primarily at the physical and data link layers of the communications protocol stack.  This includes modeling of the wireless channel itself (in multiple environments), modulation/demodulation, transmitter/receiver signal processing, multiple access, etc.
