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

Quadratically Constrained Beamforming Robust Against Direction-of-Arrival Mismatch [PDF]
, 2007 It is well known that the performance of the minimum variance distortionless response (MVDR) beamformer is very sensitive to steering vector mismatch. Such mismatches can occur as a result of direction-of-arrival (DOA) errors, local scattering, near-far ...
