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.

Asymptotic performance analysis of ESPRIT, higher order ESPRIT, and virtual ESPRIT algorithms

IEEE Transactions on Signal Processing, 1996
In this paper, 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.

Error Estimates for the ESPRIT Algorithm

2017
Let \( z_{j} \,:=e^{fj}\, (j=1,\ldots,M) \) with \( f_{j} \, \epsilon \, [-\varphi, \,0] + {\rm i}[-\pi, \,\pi) \) and small φ ≥ 0 be distinct nodes. With complex coefficients \( c_{j} \neq \,0 \), we consider an exponential sum \( h(x)\, :=c_{1} \,e^{f_{1}\, x} + \,\ldots \, + c_{M}\, e^{f_{M} \, x} (x \geq 0) \).

An ESPRIT-like algorithm for coherent DOA estimation

IEEE Antennas and Wireless Propagation Letters, 2005
Conventionally, the approaches to coherent direction-of-arrival (DOA) estimation are to eliminate the rank loss of the spatial covariance matrix. In this letter, a new technique is presented from another point of view, which reconstructs a special antenna array model based on the Toeplitz matrix whose rank is only related to the DOA of signals and ...

A Robust PAST-Based ESPRIT Algorithm With Variable Forgetting Factor and Regularization for Frequencies/Harmonics Estimation in Impulsive Noise

IEEE Transactions on Instrumentation and Measurement, 2022
The estimation of signal parameters via the rotational invariance techniques (ESPRIT) algorithm is an efficient method for frequency estimation, and it has many applications in power signal analysis. As ESPRIT estimates the signal subspaces and frequency

A novel reduced-dimensional beamspace unitary ESPRIT algorithm for monostatic MIMO radar

Digit. Signal Process., 2021
In this paper, a novel direction of arrival (DOA) estimation algorithm is proposed for monostatic multiple-input multiple-output (MIMO) radar. Due to redundancy of the received data of monostatic MIMO radar, the computational complexity of the inversion ...

Improved Cyclic ESPRIT Algorithm

2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009
In order to improve the estimation precision of the cyclic ESPRIT, an improved cyclic ESPRIT is proposed by exploring the cyclostationarity of the narrow bandwidth signals received by antenna array. The improved algorithm uses a new method to choose the frequency for evaluating the steering vector.
