<p>An adaptive beam former for adjusting amplitude is provided to simplify calculation, make convergence fast and change only size, thereby realizing a simple configuration adaptive beam former. An adaptive beam former comprises a subspace predicting unit(11) and a unit(12) for obtaining a weight vector. The unit for obtaining a weight vector obtains a correlation vector by obtaining correlation between signals received in each antenna of an arrangement antenna. And the subspace predicting unit obtains a subspace from correlation vectors of the received signal. The unit for obtaining a weight vector performs null projection of a steering vector in an interference signal subspace of the subspace.</p> |
