Abstract

We consider the signal-to-interference plus noise ratio (SINR) performance of several beamforming algorithms, taking particular account of the contribution of sources correlated with the desired signal. In addition, we derive an optimal method that maximizes SINR by combining with the desired signal estimate any components of the interference/multipaths that are correlated with it. To facilitate performance comparisons, we only consider the case where the signal directions of arrival (DOAs) are precisely known. The extension to unknown DOAs is straight-forward. Our analysis includes the first order effects of array calibration errors, and is verified by numerical simulation
