Two methods of pilot signal processing compared, for digital RX antenna array calibration. In first case, complex samples of pilot signal are buffered and averaged for each array channel, and then ratio of averaging results is computed. In second case, samples relations for different channels are computed first, and then averaged. Second method is much more resistant in the case of phase drift during signal sampling.
