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

Distributed source localization using ESPRIT algorithm

IEEE Transactions on Signal Processing, 2001
A new algorithm based on ESPRIT is proposed for the estimation of the central angle and angular extension of distributed sources. The central angles are estimated using TLS-ESPRIT for both incoherently distributed (ID) and coherently distributed (CD) sources.

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 ...

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.

Performance analysis of the VIA-ESPRIT algorithm

IEE Proceedings F Radar and Signal Processing, 1993
The VIA-ESPRIT algorithm is a computationally efficient method for direction of arrival (DOA) estimation. This algorithm uses virtual interpolated arrays (VIA) to apply ESPRIT type techniques to arbitrary array geometries. This paper presents a performance analysis of VIA-ESPRIT.

Reduced-dimensional ESPRIT algorithm for MIMO radar

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
A reduced-dimensional (RD) ESPRIT algorithm is proposed to reduce the dimension of the received data and to estimate the DOAs of multiple targets for arbitrary MIMO radar linear array configuration. It exploits the rotational invariance property of the RD virtual array and has much lower computational complexity than the methods of the same kind.

Asymptotic performance analysis of three ESPRIT algorithms

Conference Record of The Twenty-Ninth Asilomar Conference on Signals, Systems and Computers, 2002
We present an asymptotic performance analysis of three subspace-based methods for direction of arrival (DOA) estimation-the ESPRIT algorithm using second-order statistics, the higher-order ESPRIT algorithm using fourth-order cumulants, and the virtual ESPRIT (VESPA) algorithm using fourth order cumulants.
