The use of a receiving array of antennas allows the system to localize multiple sources. This estimation is sometimes simplified to a direction-of-arrival (DoA) estimation. The covariance-based (CB)-DoA algorithm is a lower complexity alternative to the ESPRIT algorithm, and yet achieves similar mean-squared error (MSE) with the same geometrical constraints. This article proposes a lower complexity...
In this paper, we consider performance analysis of the decentralized power method for the eigendecomposition of the sample covariance matrix based on the averaging consensus protocol. An analytical expression of the second order statistics of the eigenvectors obtained from the decentralized power method, which is required for computing the mean square error (MSE) of subspace-based estimators, is presented...
Recently, ESPRIT-based parameter estimation algorithms have been developed to exploit the structure of signals from strictly second-order (SO) non-circular (NC) sources. They achieve a higher estimation accuracy and can resolve up to twice as many sources. However, these NC methods assume that all the received signals are strictly non-circular. In this paper, we present the C-NC Standard ESPRIT and...
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 signals at the reception side (direction of arrival...
Adaptive array smart antenna involves the array processing to manipulate the signals induced on various antenna elements in such way that the main beam directing towards the desired signal and forming the nulls towards the interferers. Such smart antennas are widely used in wireless mobile communications as they can increase the channel capacity and coverage range. In adaptive array smart antenna,...
ESPRIT is a high-resolution parameter estimation techniques based on the translational invariance structure of a sensor array, which has recently been applied to the problem of determining the directions and center frequencies of a number of narrowband sources in a band of interest. Here, we present a simple and efficient method for the joint angle-frequency estimation (JAFE), named as unitary-JAFE...
