The interpolated ESPRIT algorithm

[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991
The technique of interpolated arrays is applied to ESPRIT-type direction-finding methods. The resulting method uses sensor arrays with arbitrary configuration, thus eliminating the basic restrictive requirement of ESPRIT for two (or more) identical arrays.

EF-ESPRIT: A simplified ESPRIT algorithm without generalized eigenvalue calculation

Proceedings of 2013 3rd International Conference on Computer Science and Network Technology, 2013
ESPRIT is an algorithm for DOA (Direction-of-Arrival) estimation. It provides a high angular resolution compared to the MUSIC algorithm, yet it has to calculate generalized eigenvalues of matrix pencils. In this paper, by introducing the sub-space decomposition into the original ESPRIT algorithm and exploiting Hermite symmetry of the correlation matrix

On the multi-resolution ESPRIT algorithm

Ninth IEEE Signal Processing Workshop on Statistical Signal and Array Processing (Cat. No.98TH8381), 2002
Multi-resolution ESPRIT is an extension of the ESPRIT direction finding algorithm to antenna arrays with multiple baselines. A short (half-wavelength) baseline is necessary to avoid aliasing, a long baseline is preferred for accuracy. The MR-ESPRIT algorithm allows us to combine both estimates. The ratio of the longest baseline to the shortest one is a

The ESPRIT algorithm. Variants and precision

2010 9th International Symposium on Electronics and Telecommunications, 2010
Since wireless communications began to take an abrupt rise, with the development of techniques which were introduced for the growth of data transfer, antenna systems were considered to be the ideal choice to obtain the wanted results. Nevertheless these techniques required the development of certain algorithms also, to facilitate the recognition of the

An iterative virtual-ESPRIT algorithm (IVESPA)

Proceedings of 8th Workshop on Statistical Signal and Array Processing, 2002
An iterative algorithm (IVESPA) for narrow-band direction-finding and waveform recovery is presented which is based on the virtual-ESPRIT (VESPA) of Dogan and Mendel (see IEEE Trans. on Signal Processing, vol.42, no.5, p.1200, 1995). IVESPA can handle the case where the data length is short and some of the sources have very small higher-order ...

Compact representation and long-time extrapolation of real-time data for quantum systems using the ESPRIT algorithm

Physical review B
Representing real-time data as a sum of complex exponentials provides a compact form that enables both denoising and extrapolation. As a fully data-driven method, the Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) algorithm

Bias analysis for ESPRIT-type estimation algorithms

IEEE Transactions on Antennas and Propagation, 1994
A statistical analysis using perturbation expansion is applied to the DOA estimation bias for ESPRIT, state-space realization (TAM), and matrix-pencil algorithms, assuming that only a finite amount of array data is available. The authors have obtained an analytical expression for the DOA estimation bias in a simple and self-contained fashion.
