Abstract
This paper proposes a transform-domain partially adaptive beamformer to reduce the computational complexity of conventional transform-domain beamformers, After transforming the input signals, the proposed beamformer adapts only those parts of the weights that correspond to the transformed coefficients expected to contain interference by using the cell averaging constant false alarm rate (CA-CFAR) processor. The false alarm rate of the CA-CFAR processor is also changed adaptively according to the variation of output power.
