Abstract
There are some mismatches for the estimation of signal parameters in mult-dimention Estimating Signal Parameter via Rotational Invariance Techniques (ESPRIT) algorithm. In this paper, a parameter pairing method based on eigenvalue fractal dimension is proposed. By linearly combining the eigenvalues and constructing a judgment matrix, the parameters are paired according to the corresponding relationship of matrix dimension. In contrast to other pairing algorithms, the proposed algorithm can achieve automatic pairing with low complexity, non-fuzzy parameters and higher robustness. Several examples are given to demonstrate the effectiveness of the proposed algorithm.
