<p>An adaptive rotation angle control apparatus comprises a communication quality approximate-expression storing part that stores a communication quality approximate-expression including, as variables, reception quality information, amplitude variation information and a rotation angle; a calculating part that substitutes reception quality information and amplitude variation information, which are input information, and an rotation angle into the communication quality approximate-expression to calculate a value of the communication quality approximate-expression; and an adaptive control part that applies the rotation angle to the calculating part, receives therefrom communication quality information, which is the value of the communication quality approximate-expression calculated by use of the rotation angle, and that decides, based on the received communication quality information, an optimum rotation angle.</p> |
