Abstract :
Optimum beamformer output SINR with one interfering signal is expressed in terms of signal spatial signatures and noise power. The expression, valid for multipath channels, leads to consistent results for the cases of no interference and strong interference. The optimum SINR calculated using the expression is compared to measured SINR achieved using an adaptive beamforming algorithm applied to data recorded using an antenna array testbed.
