Abstract:
1. A weighting parameter estimation system for estimating a weighting parameter for each of a plurality of antenna elements of a mobile terminal, comprising: a pseudobody phantom defining a prohibited space to which an electromagnetic wave should not be directed when the mobile terminal transmits a radio wave; a test wave source located in the pseudobody phantom and configured to transmit a test wave randomly polarized over entire ranges in θ and φ directions, the test wave being transmitted from all scanning points inside the pseudobody phantom; a plurality of antenna elements provided outside and adjacent to the pseudobody phantom and configured to receive the test wave transmitted from the test wave source; and a weighting parameter determination unit configured to estimate a probability density distribution of a time-dependent electric field response from the test wave transmitted from all of the scanning points and determine the weighting parameter for each of the antenna elements based on the probability density distribution such that a power level of all the randomly polarized test wave components transmitted from the pseudobody phantom becomes a minimum.
