Iterative robust adaptive beamforming
EURASIP Journal on Advances in Signal Processing, 2017 The minimum power distortionless response beamformer has a good interference rejection capability, but the desired signal will be suppressed if signal steering vector or data covariance matrix is not precise. The worst-case performance optimization-based

An Approximate Algorithm for Robust Adaptive Beamforming [PDF]
EURASIP Journal on Advances in Signal Processing, 2004 This paper presents an adaptive weight computation algorithm for a robust array antenna based on the sample matrix inversion technique. The adaptive array minimizes the mean output power under the constraint that the mean square deviation between the ...

A novel approach for robust adaptive beamforming [PDF]
International Conference on Acoustics, Speech, and Signal Processing, 2003 A robust technique for adaptive array beamforming in the presence of steering vector error is proposed. It is based on the fact that an optimized steered-beam adaptive beamformer possesses the maximum output SNR when the steering vector coincides with the signal phase vector.

Robustness of Adaptive Narrowband Beamforming With Respect to Bandwidth [PDF]
IEEE Transactions on Signal Processing, 2008 This paper addresses the robustness of adaptive narrowband beamforming with respect to bandwidth based on the loss of performance in terms of signal-to-interference-plus-noise ratio (SINR). The criterion used by Zatman to define a narrowband environment, i.e., the ratio between the jammer plus noise covariance matrix and the noise eigenvalue, is ...
