Measurement uncertainties of capacities of multi-antenna system in anechoic chamber and reverberation chamber
Paper in proceeding, 2011
It has been shown that multiple-input multiple-output (MIMO) capacity of multi-antenna system can be determined either from direct channel measurements in reverberation chamber or indirectly from antenna far field radiation function measurements in anechoic chamber (combined with numerically generated channel). In this paper, we try to investigate uncertainty of MIMO capacity obtained in these two ways from antenna viewpoint. It is found that the measurement uncertainty of capacity depends on measurement uncertainties of both efficiency and correlation, and that the former tends to dominate, given moderate correlation.
