ABSTRACT:
In an adaptive array (2000), fading rate of a user is measured by a fading rate measuring circuit (2300), and the transmit weight vector is weighted in accordance with the fading rate by a transmitting circuit (2400). Thus, transmission power is increased for a user of which fading rate is large, and thus transmission directivity control for such a user becomes possible.
