Improved power minimization based partially adaptive beamformer design
B.D. Van Veen · 2003
A technique for designing partially adaptive beamformers by minimization of output interference power was previously derived using a rather complicated approximation. The author presents an alternate derivation which clearly illustrates the nature of the approximation. A block diagram explicitly shows the modified partially adaptive system implied by the design procedure. This interpretation facilitates understanding of the limitations imposed by the approximation and suggests an improved design method.>
