Popis:	The LCMV-beamformers are widely used in many applications but to steer array pattern in some direction we need to use phase shifters or additional delay lines for pre-steering. In this paper, we introduce simple constraints in the DOA of the useful signal. These constraints have a form of a block-diagonal matrix. In a case when DOA is the broadside, simple constraints are equal to Frost’s constraints.
