Abstract

In allusion to multi-parameter estimation of a spin echo train (SET) signal in the presence of additive white Gaussian noise

a two-dimensional (2-D) parameter estimation method in a separable manner is proposed.By utilizing the rank-one property of the 2-D data matrix

the damping factor and frequency are estimated in a separable manner from the principal left and right singular vectors according to an iterative weighted least squares (WLS) method.The complex amplitude of SET is then obtained on the basis of standard least squares.The parameter estimation performance of this method achieves Cramer-Rao lower bound (CRLB) at relatively large signal-to-noise ratio (SNR) and/or data size conditions.Simulation results show the effectiveness of the proposed algorithm.
