Effect of beamforming errors on the efficacy of maximal ratio and equal gain combining
William C. Barott · 2014
Beamforming methods of maximal ratio combining (MRC) and equal gain combining (EGC) are compared in the presence of calibration errors. It is found that sufficient uncertainties in the antenna sensitivities make MRC less effective than EGC. Furthermore, the threshold noise temperature for including a new antenna in a time-limited survey is explored, and is found to be lower than previously-described results.
