Performance analysis of the minimum variance beamformer
Y. Anu, M. Wax · 2002
We present an analysis of the signal-to-interfere-plus-noise ratio (SINR) at the output of the minimum variance beamformer. The analysis yields an explicit expression for the SINR in terms of the different parameters affecting the performance, including the signal-to-noise ratio (SNR), the interference-to-noise ratio (INR), the signal-to-interference ratio (SIR), the angular separation between the desired signal and the interference, the array size and shape, the correlation between the desired signal and the interference, and the finite sample size.
