In this paper, a matrix pencil characteristic equation-based source number estimator is proposed. An enhanced matrix is defined through partition-and-stacking process by the original data on the uniform linear array, and its covariance matrix is computed, which is proved to be a toeplitz conjugate symmetry matrix. The covariance matrix elements are aligned to from a vector. A measurement matrix is...
In this paper, we consider joint estimation of the Direction-of-arrival (DOA) and channel parameters of fully correlated sources impinging on a linear array sensors in Underwater multipath environment. Amindavar et al.[1] proposed a blind techniques for simultaneous estimation of the DOA and the channel parameters based on the assumption that the source signal can be modeled by a sum of weighted complex...
This paper proposes a new method for the simultaneous estimation of the 2D arrival angles and the path delays of emitted user signals. By using the ESPRIT algorithm, we firstly formulate the problem with 3 matrix pencil pairs, where the eigenvalues of the matrix pencils contain the unknown parameters. Then a pairing free algorithm is developed to solve the matrix pencil based 3D estimation problem...
