Abstract

The current paper proposes a sequentially and linearly constrained minimum variance beamformer (SLCMV) based on a split polarity transformation (SPT) called an SPT-SLCMV beamformer. The proposed SPT-SLCMV is an improved version of an SPT-LCMV beamformer as it can minimize the degree of freedom loss and eliminate the desired signal cancellation phenomenon under coherent interference situations. These advantages are obtained by successively applying sub-constraint matrices divided from a whole constraint matrix to remove any correlation between the desired and interference signals. As a result, the proposed, beamformer can solve the degree of freedom loss while maintaining the performance of the conventional SPT-LCMV beamformer.
