ABSTRACT:
A weighting parameter estimation system for estimating a weight parameter for the antenna elements of a mobile terminal is provided. The system includes a prohibited space forming part to which electromagnetic waves should not be directed when the mobile terminal transmits a signal in wireless communications, and a weighting parameter determination unit configured to determine the weighting parameter for each of the antenna elements of the mobile terminal such that the power level of a test wave transmitted from or received in the prohibited space becomes the minimum.
