Improving the Robustness of the Dominant Mode Rejection Beamformer With Median Filtering

Abraham’s and Owsley’s dominant mode rejection (DMR) beamformer modifies Capon’s minimum variance distortionless response beamformer to force suitable constraints in the covariance matrix estimation process to reduce degrees of freedom. DMR estimates the ensemble cov...
