dc.description.abstractIn this paper, an adaptive spatial decorrelator is proposed in smart antenna systems. A spatial decorrelator was proposed in [11] which is similar to a multiuser receiver, decorrelators in DS/CDMA systems. However, the spatial decorrelator is sensitive to the DOA estimation error. Thus, an adaptive spatial decorrelator is proposed to compensate the DOA estimation error. It uses the equivariant adaptive separation via independence (EASI) algorithm [14] as an adaptation rule. It provides the robustness to the DOA estimation error. The proposed robust beamforming algorithm outperforms the conventional robust beamforming algorithm, such as, the linearly constrained minimum power (LCMP) with diagonal loading and covariance matrix tapering (CMT). And, it operates well even in the high signal-to-noise (SNR) regions.en
