Compressive & nonlinear signal processing

Adaptive direction-of-arrival estimation, sparse arrays, and measurement-matrix design — bridging theory and real-time hardware.

I develop compressive-sensing and nonlinear signal-processing methods for sensing and direction finding — adaptive measurement-matrix design, sparse and sub-sampled arrays, gridless estimation, and particle-filter-based tracking — and have validated them on real hardware.
