Prof. Swindlehurst's research interests lie in the application of detection and estimation theory to problems in signal processing, biomedicine and wireless communications.

Past projects include direction-of-arrival estimation, sensor array calibration, beamforming, time-delay estimation, system identification, blind channel estimation and equalization, space-time adaptive processing for radar, clutter modeling and mitigation, and interference/jammer cancellation. Currently, he and his students are working on problems in MIMO wireless communications, including space-time characterization of indoor and outdoor RF propagation, channel estimation and performance analysis for time-varying MIMO links, downlink beamforming in multiuser MIMO systems, and space-time processing for ad hoc networks.

Some new projects he is beginning work on: detection and feature extraction from biological signals, multipath mitigation in geopositioning systems (GPS, GLONASS), using multiple antennas for enhanced physical layer security.
