Abstract

This paper addresses methods for the reduction of autocorrelation between sampled data collected in mode-tuned or mode-stirred reverberation chambers. This leads to improved accuracy of the estimation of susceptibility or emission characteristics of an EUT. Ensemble decimation and orthogonal expansion are proposed as alternatives to conventional sample decimation. Orthogonal expansion also allows for a rigorous statistical characterization of such chambers, in particular for operation at relatively low mode densities.
