Multiple invariance ESPRIT
ESPRIT is a recently developed technique for highresolution signal parameter estimation with applications to direction-of-arrival estimation and time series analysis. By exploiting invariances designed into the sensor array, parameter estimates are obtained directly, without knowledge of the array response and without computation or search of some spectral measure. The original formulation of E...
متن کاملClosed-form multi-dimensional multi-invariance ESPRIT
A closed-form multi-dimensional multi-invariance generalization of the ESPRIT algorithm is introduced to exploit the entire invariance structure underlying a (possibly) multiparametric data model, thereby greatly improving estimation performance. The multiple-invariance data structure that this proposed method can handle includes: (1) multiple occurrence of one size of invariance along one or m...
متن کاملMultiple Invariance ESPRIT - Signals, Systems and Computers, 1988. Twenty-Second Asilomar Conference on
A h t r n c f ESPRIT is a recently developed technique for high-resolution signal parameter estimation. For the specific problem of direction-of-arrival (DOA) estimation, a decrease in computational complexity of orders of magnitude over other high-resolution methods is achieved by exploiting an inunriancc slrucltrre denigned into the sensor array. Previously, €SPR/T took advantage of only one ...
متن کاملESPRIT-estimation of signal parameters via rotational invariance techniques
High-resolution signal parameter estimation is a problem of significance in many signal processing applications. Such applications include direction-of-arrival (DOA) estimation, system identification, and time series analysis. A novel approach to the general problem of signal parameter estimation is described. Although discussed in the context of direction-of-arrival estimation, ESPRIT can be a...
متن کاملESPRIT with Multiple-Angle Subarray Beamforming
This article presents a new approach of implementing signal direction-of-arrival estimation, in which subarray beamforming is applied prior to estimation of signal parameters via rotational invariance techniques (ESPRIT). Different from the previous approaches, the beam-domain data from multiple adjacent pointing angles are combined in a way that the displacement invariance structure required b...
