MVDR beamformer model for array response vector mismatch reduction

Beamforrming algorithms attempt to extract a desired User-OF-Interest (UOl) from the background noise and interfering signals. The performance of the beamforming algorithm is evaluated based on various QoS criteria such as beampattern accuracy and signal-to-lnterference-plus-Noise-Ratio (SINR). In t...
