Abstract :
A method for echo canceling in screened rooms is presented in this paper. The method obtains a device under test (DUT) radiation model, in terms of a set of equivalent dipoles placed on the surface of a volume containing this DUT, using measured near-field data and a genetic algorithm based optimization process to obtain the different dipole parameters. From this set of dipoles, field levels under standard measurement conditions can be estimated
