Provides a new method for multidimensional frequency estimation on arbitrary grids, benefiting signal processing and related fields.
The paper extends the ESPRIT algorithm to multidimensional general grids, enabling complex frequency estimation on non-rectangular domains.
We present a new method for complex frequency estimation in several variables, extending the classical (1d) ESPRIT-algorithm. We also consider how to work with data sampled on non-standard domains (i.e going beyond multi-rectangles).
