The solution of this problem is analytically derived and the resultant robust beamformer is shown to have a similar form to the Capon beamformer, whereas the array covariance matrix and the steering vector are robustly estimated. Different from conventional methods, the impulsive noise and the ...

The theoretical covariance matrix is first estimated via the shrinkage method. Subsequently, the desired signal steering vector is estimated based on maximizing array output power under the correlation coefficient constraint and norm constraint. The original nonconvex quadratic programming problem, whose ...

To develop an adaptive beamformer against the steering vector mismatch of the signal of interest (SOI), a novel robust algorithm is proposed to estimate the steering vector of the SOI and interference- plus-noise covariance matrix (INCM) in an alternative and iterative way. That is, via deter...
To make the sensor array beamformer insensitive to steering vector error, an efficient interference steering matrix (ISM) estimation scheme for weight vector correction is devised in this paper. The basic idea of this approach is converting the training data into interference-free condition via ISM ...
A recursive Bayesian approach to narrowband beamforming for an uncertain steering vector of interest signal is presented. In this paper, the interference-plus-noise covariance matrix and signal power are assumed to be known. The steering vector is modeled as a complex Gaussian random vector that ...
