Spectral estimation of two-dimensional, NMR signals by matrix pencil method

摘要

Presents a new method based on the matrix pencil approach for estimating the parameters of two dimensional (2D) nuclear magnetic resonance (NMR) signals in noise. This method is capable of locating frequencies anywhere in the 2D plane, along with their decay rates. Simulation results are given to show the performance of this algorithm and its applicability to the practical 2D NMR problem.
