N2 - We propose a novel adaptive beamforming algorithm based on the multi-domain adaptive filtering approach (Yukawa et al., 2009). The proposed algorithm exploits, as a soft constraint in a transform domain, the information that the array responses to the interference direction should be sufficiently low. Additional operations introduced are linear transformations and a metric projection onto a closed ball that bounds the energy of the transformed weight vector. The efficacy of the proposed algorithm is shown by simulations.
